Reviewed by AJ Barlas and Fred Robinson // Photos by Lear Miller

Trek's Fuel EX range of bikes are aimed at the honest trail rider - those looking for a quality, fun bike that can handle a good variety of trails, but not necessarily something for super rowdy terrain. We previously tested the Fuel EX 27.5 , so it was fun to jump aboard the bigger wheeled brother and see how it compared.

For 2016, the Fuel EX 29 sees several changes for the better - it's slacker, offers adjustable geometry, has shorter chainstays thanks to the new Boost rear axle standard, and the rear shock has been updated to no longer feature Trek's DRCV. This was one of the only bikes in the 2016 Vital MTB Test Sessions with Boost spacing front and rear, but does it make a difference? Did the new RE:aktiv damper improve performance over a regular shock? Read on to find out.

• Aluminum frame
• 29-inch wheels
• 120mm (4.7-inches) of rear wheel travel // 130mm (5.1-inches) fork travel
• Full Floater suspension with Active Braking Pivot (ABP)
• RE:aktiv shock damping technology
• Tapered headtube
• External brake routing, internal cable routing, internal seatpost routing
• Adjustable geometry via Mino Link flip chips
• PF92 bottom bracket with ISCG05 mounts
• Boost 110mm fork axle spacing
• Boost 148mm rear spacing with 12mm through axle
• Measured weight (size 19.5, no pedals): 28.6-pounds (13.0kg)
• MSRP $4,000 USD

The Fuel EX 9 29 comes with a handful of unique features, and is highlighted by the RE:aktiv damper technology. Trek worked with motorsports specialists Penske Racing Shocks and FOX to create a shock with regressive damping. In a race car application, regressive damping is designed to be firm when cornering but supple for sudden impacts. When applied to mountain bikes the goal is similar - to provide support when pedaling or pumping but open up when needed.

Most rider inputs create low shaft speeds, while bumps create higher shaft speeds. Inside the shock, the main piston is equipped with a special spring loaded valve. The faster the shaft speed, the more the valve opens up and the more oil is allowed to flow through. Trek says the valve is capable of delivering lots of low-speed compression damping, fluid high-speed compression damping, and an instant, seamless transition between the two. Because of this Trek says RE:aktiv achieves what inertia valves have been unsuccessfully attempting for years by balancing pedaling performance with big-hit absorption without feeling harsh. The way it’s able to react so rapidly is by changing the surface area that the oil is pushing against .

The shock's abilities are most apparent in the "Climb" or "Trail" compression settings as the bike remains quiet during pedaling, but still allows the suspension to move due to ground impacts. This translates to the rear wheel moving out of the way while the rider continues to put power down. How it functions is really quite amazing, but it has its limitations and we’ve found that there is a time and a place for its use, much like any of the regular pedal platform adjustments on all rear shocks.

The spring curve of FOX’s relatively new Float EVOL (extra volume) shock closely matches the linear curve Trek previously relied on DRCV to provide, so DRCV gets the boot this time around. The shock is still proprietary due to its odd 184x48mm (7.25x1.875-inch) dimensions and RE:aktiv damper, however. To get that 120mm of travel, Trek's Full Floater suspension design actuates the shock from both ends with a one piece magnesium EVO Link on top and a concentric pivot at the rear axle known as ABP.

Boost is the other unique-ish technology that higher end Fuel EX 29 models include. We say unique-ish only because it's not commonplace yet. Boost was originally aimed to create stiffer 29-inch wheels without having to throw down the extra coin for carbon hoops. This was achieved by moving both rear hub flanges 3mm out from the center, resulting in a new 148mm axle width. Wider spacing gives the spokes a greater bracing angle, which in turn generates a stiffer wheel. This slight change also provided better tire clearance, which means that they can run slightly shorter chainstays. The front wheel also includes Boost, which takes the hub width from 100mm up to 110mm for similar results.

Additional features include room for a water bottle inside the front triangle, a PF92 bottom bracket, ISCG05 tabs, close to 19mm (0.75-inches) of mud clearance with the stock tires, optional direct front derailleur mount, and a fork with a custom 51mm offset. Aside from the stealth dropper post and rear derailleur cable (which is held taught in the frame), routing is external on the Fuel EX 9 29, which makes for easy service with no rattle. You'll find a large downtube guard for stray rock protection, but consider adding some extra protection to the stays for chainslap.

Trek offers the Fuel EX 29 in four aluminum complete builds ranging from $1,990 to $4,000 USD, two carbon builds at $5,300 and $8,400, and as a carbon frame for $3,300. There's also the option to build a fully custom bike through Trek's Project One program . Fuel EX 8 29 and above benefit from Boost, while the Fuel EX 7 and 5 29 retain 2015’s frame with standard hub spacing. We tested the $4,000 aluminum Fuel EX 9 29, which has an extra 10mm of fork travel (130 vs 120mm) over the other models.

2016 brings Trek's adjustable geometry feature to the Fuel EX 29 lineup via the Mino Link flip chips near the top of the seatstays. The geometry chart above shows numbers in the "low" setting with the option to steepen the head angle to 69.4-degrees and raise the bottom bracket by 8mm (0.3-inches). We measured our test bike bottom bracket height at 340mm (13.4-inches) in the low setting, so it's possible that the listed geometry is with a shorter travel 120mm travel fork. While slacker than the previous Fuel EX 29, at ~68.8-degrees this bike is a degree or so steeper than many other recent short travel 29ers. Thanks to Boost, Trek was able to drastically shorten the chainstays from 452mm to a much more nimble 436mm (17.2-inches), which is par for the course among comparable bikes. As you can see, it comes in several sizes to suit just about any rider.

On The Trail

Setup was a breeze thanks to Trek's suspension calculator , which provides a great starting point for air pressure and rebound. In the open "Descend" compression setting, we found the rear end to be more active during seated and standing pedaling efforts than similar bikes ridden during Test Sessions . Smooth climbs consisting of mellow to considerable grades with the occasional small rock feature saw the bike exhibit a good, nimble, and lively attitude. The bike is more enjoyable ascending than the Transition Smuggler thanks to a more energetic, positive demeanor. It’s more sporty than the static weight would suggest, and there were minimal issues with pedal strikes. Once the compression dial was set to the medium "Trail" setting, however, the beauty of the RE:aktiv damper really showed through.

In the medium compression setting the suspension was remarkably quiet as the RE:aktiv damper stepped in to allow for more power to the floor during climbs, but still provided plenty of traction on the dry, abrasive conditions of South Mountain's trails in Phoenix, Arizona. In this setting the bike required less energy to move up the hill. Climbing up rocky, stepped technical sections the bike had a great balance of control, moving through its travel smoothly while offering support, and notably missing harsh feedback that would result in it getting hung up on square edge features. It also helped with the bike's geometry, sitting a little higher in its travel, effectively resulting in a steeper dynamic seat tube angle.

Going to the firmest "Climb" mode was too much of an extreme when climbing rough sections, however, as it lost a lot of traction on relatively average grades with rough-ish patches. On smoother road climbs it was great to have it locked out, though, with minimal suspension movement while practicing good pedal technique.

Overall, we found the Trek Fuel EX 29 to be an above average climber. It's not a snappy XC style ascender, but is spirited enough and assists the rider rather than feeling like a dead sail. It is by no means a race bike out of corners or up moderate pitches, but does climb reasonably well with the stock 32-tooth chainring. If you're inclined, the bike will provide better antisquat traits with a smaller chainring.

Even with a swapped out 50mm stem, we felt as though the cockpit on the size 19.5 bike we tested was a little long while seated. The reach, on the other hand, was a little short - this is predominantly due to a slack 67-degree actual seat tube angle. On moderate to steep punches we found it a bit difficult to get up over the front end while in the saddle, and would wind up riding way up the nose of the seat in order to compensate. Moving the seat forward on the rails helped with this as well.

The 50mm replacement stem took place of the stock 70mm Bontrager Rhythm Comp. We should also mention that the Bontrager Race Lite 750mm (29.5-inch) wide bars were swapped out for something a tad wider. These changes created a more comfortable setup for how we prefer to ride. Even so, a steeper seat tube would result in it climbing more favorably, especially on steep technical grinds.

While descending smoother, lower grades with the compression lever set to Trail, the bike responded well to rider input and zipped along at a solid pace when exiting corners or putting a few pedal strokes in to get back up to pace. In this setting it tracked reasonably well in loose over hard conditions, though it was easier to break loose under aggressive cornering. High speed descents and g-outs often overwhelmed Trail mode during descents, however, so flipping dials is a must do to get the most out of the bike.

On the same type of trails with the compression wide open the bike was much more willing to being pushed hard into corners, garnering increased traction but losing some of the sporty attitude exhibited in the medium compression mode. This resulted in more required rider input and planning in order to pick up over obstacles and square edges.

Getting up to speed in rough terrain we noticed the suspension tracks well through all types of smaller hits. The bike comes out of deep compressions well and has a nice bottomless feel without feeling harsh. We never really felt the end of the travel despite using the full amount many times, even though there are no volume spacers in the shock from the factory.

During successive high speed hits it never packed up or felt like it was hanging up. However, the Fuel EX didn't exhibit the same level of confidence inspiring stability that we found with the Transition Smuggler or Evil Following, with the Fuel EX requiring an extra level of rider guidance in order to keep the bike on line. In fact, due to its tendency to wander we had a couple of "moments" in parts of the trail where the Transition and Evil would just motor along comfortably. In rough conditions the bike feels deceptively tall despite running some similar numbers to its competitors. The suspension didn’t give what we would describe as a planted ride, and due to its softer, more active, and lively nature it preferred to be ridden with more of a playful attitude. One potential way to boost the bike's overall stability in the rough would be to run a little more sag and add a volume spacer for a more progressive but deeper feel.

Here's the suspension in action:

Regarding the Boost wheels, after a few days of good hacking the rear wheel eventually lost some spoke tension, and any half decent hit or hard corner would result in horrible noises coming from the rear wheel flexing. As such, we were unable to truly discern any benefits to the wider system at that time. It should be noted though, that it's is fairly typical of a new wheelset to require some attention after initial break-in. Our second tester got to ride the bike after we had adjusted the spoke tension and felt the wheels went unnoticed, essentially performing as they should and feeling similar to that of a well trued, solid 650b wheelset. The frame was stout, too. In short, Boost works, but only when the wheels are properly tensioned.

Trek’s $4,000 Fuel EX 9 29 model is pretty competitively priced, though four grand can go a long ways with other "consumer direct" brands, especially when you consider the components. Even so, this bike comes ready to rally with solid FOX suspension front and rear, a SRAM Roam 30 wheelset, trustworthy Shimano XT brakes with dual 180mm rotors, a RockShox Reverb Stealth 125mm dropper, and a reliable SRAM X1 1x11 drivetrain.

The 130mm travel FOX Performance 34 Float fork provided a stable ride with minimal adjustments, and the suspension giant seems to have moved away from the issues that plagued them a couple seasons ago. The fork used its travel well while offering a good amount of support. It never felt overly active and was generally quieter than the rear of the bike.

For the terrain we were riding, we would swap out the stock 2.3-inch tubeless Bontrager XR3 Expert tires for something with a bit more meat. While the XR3 tires were okay, they didn’t inspire a great amount of confidence in loose over hard corners and their lightweight sidewalls added to the bike's instability in high speed chunder. That said, these were one of the only thinner sidewalled tires to not experience a puncture during Test Sessions, so that's a plus.

Aside from the rear wheel not having proper spoke tension when we first hopped on the bike, the SRAM Roam wheels were solid. After tightening up the spokes our second tester was able to get on without any of the annoying, sketchy sounding flex observed during the first tester's rides, and went on to note that the wheels felt inline with a sturdy set of 650b wheels as claimed. At the end of our test the rear wheel was only slightly out of true.

As mentioned above, we swapped out the somewhat narrow low-rise bars and longish stem for something that better suited the descents, but realize that these cockpit choices are a personal preference. The supplied grips were not the most comfortable either, with a very thin, hard rubber that felt pretty harsh on rough trails.

Long Term Durability

Outside of regular maintenance like tires, brake pads, and checking the spoke tension of the wheels, the Trek Fuel EX 9 29 appears ready to go the extra mile. Thanks to some clever cable routing we don’t foresee any issues from excessive rub, and given the rest of the decent quality components and good construction there is no reason to be concerned with the long term durability of the bike.

Towards the end of our last ride we did notice a creak developing in the pivot located just above the bottom bracket. Simply snugging up the hardware resolved the issue.

Trek backs the frame with a lifetime warranty, though there is a five year condition on the swing arm and one year on paint and decals.

What's The Bottom Line?

Trek’s Fuel EX 9 29 is a good value with some serious suspension technology that only adds to the fun times provided by a short travel 29er. You've got to be willing to flip some levers mid-ride to really see what it's capable of, so "set it and forget it" riders may not appreciate all the bike has to offer. The ride's conservative geometry works well on a range of terrain and features, and though the bike doesn’t really nail either the climbs or the descents, it’s a solid all-around steed. While very lively and active, it lacks a super confidence inspiring ride when things get truly wild. Some minor suspension tweaks and a burlier set of rubber could make it a more stable descender.

Take a look at the new Fuel EX and you will quickly see Trek has fully redefined the model. The 2016 Fuel Ex 29 was a step in the right direction, but it was a timid half-hearted step that left the rider wondering what if…? What if it came spec’d with a stiffer fork, more travel and a slacker headtube? The team at Trek delivered and the 2017 bike answers these questions. It now allows the use of 29” or 27.5+ wheels and is one of the stiffest frames in the category, featuring a totally new geometry that’s slacker and longer than its predecessor.

2016 Fuel EX 9.8

• Add to quote

Hello guys. I am in the market of buying a new mtb. I started at the beginning of summer with a 2015 Trek Marlin 7. Great bike for the last 6 months to make me realize this is the sport I want to pursue. With that said, there is also been 6 months where I have been able to see where I would want improvements. Instead of doing upgrades, I want to go with a new bike altogether. I know testing them will be the best for me, but just based upon your feedback, I would like some insight on my choice. Right now I am leaning towards the 2016 Trek Fuel EX 9.8, which is a carbon bike. It's pretty expensive, but I am thinking about going all out so I can have a bike for years to come without regretting me decision. Do you guys think this is a foolish decision since I have only been riding 6 months? Is carbon overpriced for it's benefits? Are there other suggestions from Trek (I just like the brand) that you'd recommend? Thanks and Merry Christmas to everyone!  

imo the fuel ex is the best trail bike on the market. but the 9.8 seems a bit overpriced to me; crazy nice shock, reverb, carbon frame, and xt but performance line fork and porky wheel set. with just a quick look a camber comp carbon seems almost as nice (as a 9.8) but a good deal cheaper. and if carbon isn't a must check out the ex 9.  

Thanks for the input! I really like Trek, especially what they've done with the rear suspension, but I wouldn't rule out that Specilaized you mentioned either. As far as the Fuel EX 9.8, I've heard only good things about it online except for what you just named. Almost everything is good, but they skimpt on a few things. Carbon isnt necessarily the deciding factor, but like I said in my OP, if I'm shelling out the cash for a permanent bike, it may just be worth it. Do you think that EX9 is more suited for its price range?  

I'm basically in the same position as you. I purchased a superfly 5 and now im wanting more. Demo'd a 2016 fuel ex 9. Such a better bike for where i've been riding. Smashed PRs without even trying. But I feel l'd be wanting more, so going the direction of the remedy 9.8.  

Brodon said: Im sure some of the internet bench racers will come out of the woodwork and recommend some boutique bike you (and probably they) will never be able to testride. The fuel ex is the best all around bike in the price range if you can only have one bike in my opinion. I bought an ex 8 after demoing the camber comp and a few other highly competetive bikes. The 9.8 is awesome but still leaves a few parts that would be upgradable, and the carbon bike is one that would be well worth upgrading down the road. That said, it is so much more bike than you are used to riding already and you really wont want to upgrade it for a while imo Click to expand...

On the remedy 9.8 there are a few things im considering changing. Front travel to 150 or 160mm (the forks are adjustable) Change out from the 2x11 to a 1x11 Tubeless Wider bars/shorter stem, if I can't get the bontrager 50/60mm stem and 820mm wide as a factory/shop swap. I don't really feel as these are major upgrades or changes. I might consider a wheel swap at a later date.  

There seems to be a big gap between the top 9.8 models and the very top 9.9's in the Trek lineup. Looking at the top fuel 9.8SL - full carbon, great spec and carbon wheels. This is roughly 5K and the 9.9 add's RS1 and maybe a little higher spec carbon wheels but the price goes up 4K. Not sure the additional 4K justifies the upgrade as the SL is pretty sweet and light out of the box (at least the top fuel models).  

The 9.8's have always been the best bang for the buck in Trek's bike lineup, if you want a carbon frame. I just bought Fuel EX 9 and have been completely satisfied with it. I set it up with a XR-4 tire up front, but it is otherwise stock. I may rebuild the wheels with wider carbon rims, but haven't decided just yet. I was between the 9 and the 9.8, but wanted 1x11 instead of 2x11. I figured the 9 with upgraded rims was still less expensive than the 9.8. Not sure you can go wrong with either though.  

The fuel 9.8 is a 2x11 120mm bike and weighs about 1lb less than the Fuel EX9 The Fuel EX9 is a 1x11 120/130mm Bike Both have same fork EX9 has 10mm more travel. and yes it effects the Geo enough to feel it. 9.8 has the new M8000 brakes EX9 has just the normal XT from that one is Shimano (9.8) other has SRAM (EX9) I didn't do the 9.8 over my EX9 due to the color Mainly. Friend has a 9.8 that I have ridden on and it feels almost the same as my EX9, the 10mm xtra travel you can feel in the HA though. Which was another selling point for me. Easy to add the travel though. But I love the color of my EX9 either way, both are awesome bikes  

FWIW, my EX9 came with the M8000 brakes. It was from the most recent batch to hit warehouses  

Lucky. Mine didn't but it was he first Batch of bikes  

If you can afford it I say buy it.  

EX9 was my choice. Love it. The new Fox 34 FIT4 fork is fantastic. The new rear shock is great too. I specifically was looking for a SRAM 1by and this bike has it with X1 level components. The XT brakes (mine are M785) are solid. The SRAM Roam wheels come with molded rim strips and valves so are a breeze to set up tubeless. I'm perfectly happy with aluminum for a full sus mtb. CF benefits don't quite accrue in the same way as they do for road or rigid bikes.  

Carbon FuelEX is absolutely a top performer for an all-around bike... although I'd wish for a 140mm fork on it, and a Fit4 or Charger damper to keep up with the remarkable rear suspension performance, and also fix the steep head angle (steep for all mountain uses - but it's pretty brilliantly set for a Marathon XC bike). If they could make a 9.7 Carbon Remedy (and slap a GX drivetrain, Deore Brakes, and the Bontrager Wheelset off the EX-8) -- that bike would be positively glorious, but would probably take huge chunks of sales from both the EX 9.8 and EX-9. As a long-legged XC-Trail bike, the 9.8 is the best value in the lineup. At properly discounted pricing, it's a great bargain (at MSRP, it gets crushed by all sorts of boutique offerings, as alluded to above - Evil Following, Pivot Mach429, Yeti SB4.5c, RockyMountain Instinct 970MSL, as well as the Specialized Camber Carbon Comp). The biggest size makes no sense (the 21.5" is basically just as long, and it would require a real giant to need that much BB-saddle length - yet it still ships with a 125mm dropper, which is dumb), but if it rides how you want out of the box, it's really hard to beat.  

I have demoed both the EX9 and the 2016 Camber Comp Carbon. The Trek pedals much better! The Specialized feels like it's full of lead compared to the Trek. I believe it's actually lighter, but even in propedal it's a dog. The EX rear suspension and Fox 34 are also way plusher than the Camber. Downhill handling could go either way, but all around the Trek is the way to go.  

I'd bet money this was nothing more than the suspension setup and air pressures being miles closer for you on the Trek your rode than the Specialized - especially if the shop just finished showing off the Autosag (which works acceptably only for people with no willingness to use a shock pump themselves). This is the only way a bike can be plusher AND more efficient on basically the same running gear. From the manufacturer recommended settings, I've never done anything except come down on fork air spring pressure (and eventually come up a touch on LSC), and come up on shock air spring pressure. I went so far as to put volume spacers (or Float oil) in forks so I can run even lower spring pressures, even if it means I have to run it in a Trail-midrange LSC type modality to get efficient seated pedaling, I've found this to be the best combination of small bump compliance. It does end up hitting practical limits on mid-range support and bottoming, but the sweet spot is surprisingly large with this tuning approach. Shocks - deliberately try bracketing in the sag from a wider area than you'd expect; mostly try pushing each setting from a known good point until it starts to not behave yow you'd like, and understand exactly what about it you dislike. Take that adjustment off the other extreme, then keep working at it.  

What is everyone running regarding fork and shock pressure compared to the recommended Trek value ? For my weight (90kg all geared up), Trek recommended 91psi for the fork and 215 for the shock... I am actually running what they recommended (210) for the rear but much lower for the front (70).  

At 175-180 rider weight I'm running 13mm rear seated sag and 21mm front standing sag at 225 psi rear and 70 psi front. That's on an 2016 EX9 with 130mm Fox 34.  

if you are worried about geo or travel in the front fork of a ex9 v 9.8, can't the fox 34 be adjusted to 130mm, to a maximum of 140mm frame wise?  

Yeap. Air shaft 140mm for fuels. 160mm for remedies  

I don't mean to derail the thread but can anyone weigh in on when it makes sense to get the fuel ex 9 vs the 8? I am looking to upgrade from my trek 6500 I purchased and have been riding since 1998. I'm pretty excited to upgrade and am saving up to do this in the spring. I am in a financial situation, however that makes me question the sanity of ME paying up to $4000 on my new bike. I have made a hard tail bike last 18 years and plan on getting my money's worth out of this next bike. This makes me think, what is an extra $1000 over at least 10 years? Then I imagine having to finance a couple grand on the difference and for someone trying to get out of debt, this seems irresponsible. I will be out of cred card debt this summer but am trying to figure out if the upgrades btwn the 8 and 9 are worth the scary price tag. I realize I a, posting this on a thread about a $5,000 bike and also mention of $8,000 bikes. I have no judgement on people who can afford those bikes and would get one if I could but am wondering for someone in my position that will feel it at $2,800 and REALLY feel it at $3,900, are there reasons to consider the 9 instead of 8 that could be discussed here?  

Fuel EX8 2x10, Fox 32 Bontrager rims/hubs. KS dropper basic Shaimno brakes 120/120 travel Fuel EX9 1x11, Fox 34 ( yes it does feel a lot stronger) SRAM Roam rims/SRAM hubs, (they are ok) Reverb dropper (I'd rather have the KS), XT brakes 130/120 travel my opinion, Id buy the EX9 if i had the funds./ I own one. I love it.  

If money is such a problem (sounds like it is right now) then I'd go for the EX 8 - its already a great bike and you can upgrade parts over time IF you find you need to. The only caveat I'd put on that is if you're a Clyde (over 100kg) in which case the Fox 32 might be too flexy for you and upgrading that alone would cost the difference to the EX 9. I've got the EX 8 and don't regret it at all. The components are all a huge improvement over my previous 5 year old trail bike. The fork is so much better than my old open bath Fox 32. For most people the bike won't hold you back as much as skills and fitness will. The fact that your previous bike lasted 10 years says a lot and suggests you probably won't miss/regret getting the affordable option.  

Thanks dischucker, I fluxuate between160 and 170lbs. I KNOW the difference between my 18 year old hard tail that has a rock shocks Judy with maybe 60 travel (when it worked) will be eclipsed by anything.  

I second the EX8 suggestion. The differences between the 9 (which I bought) and the 8 will be subtle compared to the differences with your current ride.  

GT5050 said: Just an update, I received my Hope Spring and Pawl set from Jenson USA today and installed them in my SRAM Roam 30 rear wheel on my EX9. They fit perfect, engagement is much better obviously as I doubled it, in fact engagement and sound of the freehub now is very reminiscent of what I'm used to with my former Mavic SLR wheels on my old bike. Maybe not the most direct out there but pretty good now, very happy with this $20 investment. Definitely gonna hold me over until I am ready for a new wheelset. Here's the link to the ones I installed: Hope PRO2 Hub Spring and Pawl Set > Components > Wheel Parts > Hub Small Parts | Jenson USA Click to expand...

My suggestion would be to do a bit more research and hit up the used market. Find a 1 or 3 year old that's been lightly used for half or a third of the price. Take it to a friend who knows bikes or a shop to look over if you don't know about the condition. Use the money you saved to upgrade or for some good beer.  

Or just buy a Remedy 8  

I have the 8, and if i could have afforded it i eould have gone with the 9 for the upgraded fork and a few other things, but i can tell you that the new 32 fox is really damn good. I really dont feel much if any noticeable flex from it and the damping is very good. Main reason id like the nine is just to have the extra 10mm travel. Im not into dropper posts, so i cant say which is better, but the ks on the 8 is pretty heavy. I dont use it so i am putting a rigid post on mine. I converted to 1x10 for ~$35. I am really happy i did. After this the only thing i may upgrade is the wheels for a little lighter set down the road. Favorite bike ive had.

Thank you brodon and kosmo. I appreciate the perspectives and extra details. I think my plan is to see how much I can save up by May (unless there is some incentive from a lbs to buy sooner) and get whichever one I can afford by then. I am interested in possibly upgrading wheels. Has anyone on here done so and if so, what wheels do you recommend?  

This year, I'll be rocking some Nox Teocali rims with DT350 hubs. I don't quite have them yet, so can't shout too loudly about their greatness, but they sure have a great rep. Last year, I went cheapo and ran an existing pair of Roval Carbon wheels I had from the prior year. Like every hard rider I know that tries for two seasons on these, I had spoke breakage issues on the rear wheel. The front held up fine. Let us know when you make a decision and pull the trigger!  

If sub $400 you'll be struggling due to Boost hubs... Try and pickup some Novatec Boost hubs and lace them to some ARC 24 or 27 rims or something similar.
