We are very familiar with 29er hardtails from Fuji Bikes having previously reviewed their Tahoe 29 (alloy frame) and older model SLM (SLM stands for Super Light Mountain). For this year, Fuji made a lot of changes to their flagship 29er carbon racer. The frame material, tube shaping, geometry and stiffness have all been updated resulting in a frame that is lighter, stiffer and more capable than the previous version. It also now has mounts for two bottle cages with the exception of the size small frame (something our reviewers previously dinged the SLM for).
The Frame
The frame itself is now Fuji's top level c15 carbon (instead of the previous version's c10) that is constructed with internal bladders to eliminate voids. It is also a monocoque design for added strength and rigidity. The tubes have been reshaped including the ovalized downtube for increased stiffness and power transfer. By refining their carbon molding process, Fuji was able to shave nearly 300 grams from the previous SLM with the frameset weight coming in under 1000 grams.
The Fuji SLM 29 has a short tapered head tube which helps keep the front end from getting too high, which is especially helpful for shorter riders and smaller frames. The shorter front end puts the rider in a more aggressive position. The chainstay length is 430mm and helps keep the bike nimble (in a 29er manner of speaking) and the overall wheel base is shorter. The lower standover is again, helpful for the shorter 29er rider.
Fuji's Marketing Manager, Stephanie Genuardi gives us an in-depth explanation of their reason for using a press-fit bottom bracket, "We use a Press-Fit 30 (PF30) bottom bracket on the SLM 29. Eliminating the BB cups and using an alloy spindle enables us to reduce the weight of the crank and BB assembly by up to 18%. We also feel that PF30's larger bearings than standard thread-in BB cup systems provide longer bearing life and increased stiffness. And with the PF30 positioning the bearings inside the BB shell, the crankset can, therefore, be made narrower - increasing ankle clearance."
Out back, the SLM 29 uses a 142 x 12mm rear thru-axle that strengthens lateral stiffness in the rear triangle. It also features an asymmetrical seat tube that allows for increased rear tire clearance. All of these changes and updates work together to create a ride that is efficient, light but won't beat you down for the long haul.
The monocoque carbon frame is light, stiff and features nice internal cable routing.
The Fuji SLM 29 1.1 comes in 5 models (1.1, 1.3, 2.1, 2.3, 2.5) in varying build levels with the 1.1 and 1.3 using the c15 carbon and the 2.1, 2.3 and 2.5 using the less expensive c10 carbon. As the top of the line model, the 1.1 has an MSRP of $5799. The SLM 29 comes in 4 frame sizes - S (15"),S/M (17.5"), M (19"), M/L (21"). The model we tested is the 15". The matte carbon black finish with red and white highlights provides a simple and clean look that is easy on the eyes.

Parts Spec
Suspension duties are handled by a Fox 32 FLOAT 29 fork with CTD that provides 100mm of travel. The 15mm thru-axle keeps the front end stiff and tracking true. One nice touch is the bar-mounted remote lockout and just like everything else, the easier it is to access, the more you will use it. The Descend and Trail mode on the fork works so well that we rarely used the Climb mode. Come race day, you will be happy to have such easy access to the lockout, however. For a bike with such a sharp focus on racing, the 32 Float 29 is a perfect match.
Shimano XTR derailleurs, shifters and brakes pair up nicely with the Praxis Works rings and Oval cranks.
The drivetrain is mostly top of the line Shimano 2x10 XTR parts with the exception of the Oval hollow forged cranks, Praxis Works cold forged chainrings and bottom bracket and KMC X10 chain. The Shimano XTR disc brakes performed awesome and we had no issues with them throughout our entire long term testing. The inline mounting of the rear caliper (between the chainstays and seatstays) is also a nice touch, this position performs well (stays out of harm's way) and just looks right. For 2015, Fuji has already changed the spec on their top level SLM from a 2x10 to a 1x11 system, which is definitely the right call for a race-focused bike.
Since Fuji Bikes and Oval Concepts are part of the same parent company (ASI), the SLM 29 is peppered with a good selection of Oval components. Oval brand part include the bars, stem, grips (made for Oval by Kraton), saddle, seatpost and the aforementioned crankset. The 710mm bars struck a good balance between leverage and raciness. The long-ish stem shows the race-nature of the bike. The saddle is again, race-oriented and a bit on the firm side. This is one part I would probably change if this were my personal bike. No dropper post here and no quick release either since most racers will want to set and forget when it comes to saddle height.
Oval is owned by ASI sports, the same parent company of Fuji Bikes.
As we always say when it comes to 29ers, wheels are a key component spec since they can make or break the ride. On the Fuji SLM 29, we were pleasantly surprised at the performance and weight of the Sun-Ringle Black Flag Pro SL wheels. These were truly a standout spec. The hub bearings are super smooth and spin for days. Just pick up the rear of the bike and spin the back wheel for a demonstration. The 15mm thru-axle front and 142x12mm rear kept things stiff. These wheels were not flexy and tracked true even when we didn't pick the best lines. The Schwalbe Nobby Nics are a good choice for all around trail use as well. Fuji has switched to the more race oriented Schwalbe Thunder Burts for 2015.
Here is a complete product spec list:
Geometry
Geometry on the Fuji SLM 29 is definitely race oriented, with a forward weight bias. The shorter rear and longer cockpit keep you in an aggressive position to charge the climbs but at the same time, descending on the SLM is not skittish and is in fact, one of the strong points of the entire bike. If you haven't ridden a 29er before and you are afraid that it will be too sluggish or ill-handling, the SLM will lay all of that to rest. On the climbs, the short chainstays and stiff rear end allow for an efficient transfer of power and on the descents, the carbon frame and big wheels allow you to carry more speed than on a similarly built 26" bike.
I rode the small (15") size Fuji SLM 29 1.1 and it was a solid fit for me at 5'5". Occasionally, I am between a small and medium, but the small gives a more nimble overall feel. The short head tube is welcome to keep the saddle/bar position reasonable and the bike never felt too big. As I've said before, 29ers aren't just for tall riders and riders of all heights should give 29ers a spin. There's no reason everyone shouldn't be allowed to feel the climbing and rolling advantages of a 29er.
The claimed wheelbase is 42.8 inches on our 15" and helps provide a stable ride. Our measured weight for the 15" without pedals is 22.3 lbs which is slightly higher than what is stated on Fuji's website.

The Ride
During our long term test of the Fuji SLM 29 1.1, we were not surprised to learn what a great climbing bike this is, ready to tackle any XC or endurance race that you might want to enter. The frame provides stiff, efficient transfer of power in a package that isn't so stiff that it wears you down over the long haul. But what was surprising was how much fun this bike was on the descents as well. The carbon frame and big wheels combined to make this a bike that could really handle when the trail turns down. All of the upgrades and changes to this model have combined to make it a bike that is better than just the sum of its parts.
Big wheels doesn't automatically equal slow or sluggish when done properly. With quality frame construction, smart geometry and high end spec, the Fuji SLM 29 1.1 proves this. We rode the SLM for the Sea Otter Classic MTB Gran Fondo and it was a perfect course for this rig. Over the 24 miles and 3400 feet of elevation, the SLM was light, agile and comfortable - a winning combination in our book.
The only downside is the price. Top of the line models never come cheap and the SLM 1.1 is no exception. $5799 is a lot of money, but the good news is that this bike can be found for less than that. Even better, the price has actually gone down for 2015.
Conclusion
Clearly targeted towards the racer, the Fuji SLM 29 1.1 can excel as a race rig. But its appeal goes beyond the race course and handles great (for a hardtail) on the descents as well. Top notch parts spec, excellent geometry and big wheels all add up to a ride that is fun AND fast. The ride of the c15 high modulus carbon is stiff and efficient and the dialed geometry keep things nimble and capable. This may not be the lightest bike in its category, but sometimes there is more to be said for a bikes overall ride than just being the lightest.

"The Fuji SLM 29 is ready to race right off the shelf and will serve you well in this regard. However, this bike has appeal for those of us who don't pin a number on every weekend. We were pleasantly surprised at how much fun this bike was on the downhills as well as the uphills. Big wheels help, of course. A few smart upgrades would lighten this bike and make it 5 chili pepper worthy."

"The full MSRP is a bit high, but Fuji's models typically have a much lower "street price". End of the year bargains can be had right now on the 2014 models and Fuji has even lowered their prices for 2015."
Perhaps as a sign of the times, for 2015 Fuji has expanded the SLM model line from five 29er models to a total of seven including three with 27.5 wheels. The price of the new SLM 29 1.1 has also dropped down to $5249 and is now shod with Schwalbe Thunder Burts (a more XC race-oriented tire). The 27.5 hardtails sound intriguing but the performance of the 29ers will be hard to beat.
