When the Troy was first released back in 2013 there weren't a lot of other aggressive 140mm travel trail bikes. Most bikes had more or less rear travel, but the Troy spanned that gap and established itself early on as a playful yet highly-capable ripper in the 27.5 all-mountain category. Fast forward to the current model year and the Troy gets a new carbon frame that improves stiffness and responsiveness, as well as more progressive geometry that gives the bike some extra stability when the trail points downward. These are all good things, but what's really got us excited is that it's now available with 29-inch wheels. We're advocates for the larger wheel size as it's hard to deny the efficiency and rolling benefits associated with wagon wheels. Once you're up to speed they hold their momentum and don't get hung up as easily in braking bumps, chunky rock gardens, and generally rough terrain. Combine these advantages with DeVinci's Split Pivot suspension platform that stays fully active while braking, and the Troy Carbon 29 Mountain Bike Frame is ready to attack the trail with newfound haste.
The redesigned frame is now entirely carbon fiber including the rocker link. The result is a stiffer and more responsive frame that saves about 1.5lb compared the aluminum version. DeVinci ups the stiffness even more by moving to Super Boost 12 x 157mm rear spacing. While the transition to a new hub standard might cause a bit of uproar, the truth is that 157mm rear spacing has been around on downhill bikes for quite some time. Super Boost simply widens the hub flanges to improve the spoke bracing angle, resulting in a stiffer rear wheel that's better able to resist torsional forces caused by cornering, braking, or charging through technical terrain. This is especially noticeable on 29er wheels as they have a greater tendency to flex. In addition to these stiffness benefits, Super Boost allows DeVinci to keep the chainstays super short while still clearing a 29 x 2.4in tire and up to a 38t front chainring—giving you a wide range of tire and gearing options. DeVinci also made the switch to a threaded bottom bracket, simplifying maintenance while eliminating the creaks often associated with press fit BB's.
Taking a closer look at the Dave Weagle-designed Split Pivot suspension, the design consists of a main pivot and a concentric rear axle pivot separated by the chainstay (hence the name Split Pivot), as well as the brake link (seatstay) that floats between the concentric rear axle pivot and the rocker link that controls the shock. The floating brake link isolates braking forces from acceleration and suspension forces, resulting in uncompromising traction when you're charging across rough terrain—even while braking or pedaling. Many suspension designs have a tendency to firm up a bit under braking, reducing suspension sensitivity through choppy terrain and thus losing some traction. DeVinci's Split Pivot remains fully active, soaking up braking bumps and squared-edged hits effortlessly while retaining a supportive mid-stroke for pedaling, climbing, and popping off lips and rollers. When you near the end of the travel, a smooth bottom out progression prevents harsh landings. Suspension performance is further improved by the move to a Trunnion-mounted metric shock that pivots on bearings rather than bushings, reducing friction for a more supple suspension action.
As we mentioned above, the new Troy sees revised geometry that gives it some extra stability at higher speeds or while navigating technical descents. This comes in the form of a slacker head angle and longer reach, inspiring some extra confidence to stay off the brakes and let it rip. The stubby 17-inch chainstays balance the bike's downhill prowess with playful trail manners and nimble handling, keeping things fun on tamer trails while giving the bike the ability to pick lines and navigate corners with precision. Despite these geometry changes the Troy retains the ability to adjust its geometry via a flip-chip, which has been conveniently relocated to the lower shock mount for easier access. The flip-chip alternates between the default "low" position and a "high" position that raises the bottom bracket and steepens the head angle, improve pedaling performance on big days with lots of climbing.
The Troy is constructed using DeVinci's MTB-specific DMC-G carbon lay-up. Using EPS molding, DeVinci creates a monocoque carbon frame with flawless consistency throughout the carbon layers, eliminating resin-pooling and inconsistencies that can negatively affect the strength of the frame. DeVinci puts a lot of emphasis on frame strength and rigidity, and while some might argue that their frames are overbuilt, we appreciate the bombproof and stiff construction that inspires absolute confidence when you're smashing through technical terrain—even if it means a little extra weight. It also allows DeVinci to offer a lifetime frame warranty to the original owner. The frame has internal cable routing for clean lines throughout, and comes with molded frame guards for the downtube and chainstay to protect your investment from impacts while silencing chain slap. The frame also has a two-position bottle cage mount, widening the range of mounting options to allow room for larger water bottles while ensuring there's enough clearance for standard bottles should you decide to throw on a coil shock.
