Devinci
Troy STEagle 90 12s
The fifth-generation Devinci Troy ST is the short-travel counterpart to the redesigned Troy platform, aimed at riders who want a modern trail bike with contemporary geometry and frame features but without stepping into longer-travel, more enduro-leaning territory. It uses Devinci’s Split Pivot suspension layout with 130 mm of rear travel paired to a 140 mm fork, putting it squarely in the aggressive trail category rather than downcountry on one side or all-mountain on the other. The concept is straightforward: retain the capability, stability, and practical details of the new Troy chassis, then tune the package for a quicker, more responsive ride.
What distinguishes this generation is that Devinci did not treat the ST as a stripped-down variant. It shares the same core Gen-5 frame architecture and utility features as the standard Troy, including Boost 148 spacing, a UDH rear derailleur hanger, threaded bottom bracket, internal cable routing, and the SHED downtube storage system. Wheel sizing is also integral to the design rather than an afterthought, with 29-inch wheels on M through XL and 27.5-inch wheels on XS and S, combined with size-specific chainstay lengths to preserve handling consistency across the size range. In the market, that places the Troy ST as a well-rounded, high-feature trail bike for riders who value balanced geometry, practical frame standards, and a shorter-travel setup intended to feel more agile than the longer-travel Troy.

Geometry & fit.
6 sizes published.
The Troy ST’s geometry is clearly aimed at current aggressive trail-bike expectations. Across the size range, the head tube angle is a consistent 65 degrees, which is slack enough to add confidence on steeper descents without pushing the bike fully into enduro territory. Reach numbers are contemporary and fairly generous, from 423 mm on XS to 508 mm on XL, with 468 mm on M and 488 mm on L. Combined with wheelbases of 1158 mm to 1280 mm, that points to a bike that should feel planted at speed while still fitting within the shorter-travel, more maneuverable brief. Effective top tube lengths also scale sensibly, from 537 mm on XS to 654 mm on XL.
The seat tube angles are notably steep, ranging from 77.1 to 78.8 degrees depending on size, which should help center the rider for seated climbing and keep front-wheel weighting more consistent on steeper ascents. Chainstay lengths are size-specific, with 435 mm stays on XS through M and 445 mm on L and XL, a useful choice for maintaining front-rear balance as the front center grows with size. That, along with the mixed wheel-size approach for smaller frames, suggests Devinci prioritized proportional handling rather than simply scaling reach. Stack heights range from 571 mm on XS and S to 632 mm on XL, reinforcing the bike’s modern, upright trail fit rather than a low-slung race posture.

The lineup.
3 builds, ranging $3,099 – $5,499.
The Troy ST is offered in three builds: GX AXS 12s, Eagle 90 12s, and Deore 12s. That spread suggests a lineup intended to cover a broad range of buyers, from riders looking for a higher-end wireless drivetrain option at the top of the range to more budget-conscious buyers who still want the same Gen-5 frame and suspension platform. With only the build names provided, the clearest distinction is drivetrain tier, with GX AXS positioned as the premium option and Deore as the likely value entry point.
Even without full parts lists or pricing, the structure of the lineup indicates that Devinci is using the same core Troy ST chassis across multiple price levels rather than reserving key frame features for upper trims. That matters on this platform because the frame itself carries much of the bike’s appeal: Split Pivot suspension, SHED storage, threaded bottom bracket, UDH compatibility, and current axle and routing standards. In practical terms, the lower-cost builds should still deliver the same geometry and frame functionality, while the higher-end options are likely aimed at riders prioritizing drivetrain performance and overall spec refinement.
