Trek Supercaliber SL 9.7 GX AXS Gen 2 Performance on the Trail
At the core of the Trek Supercaliber SL 9.7 GX AXS Gen 2 is Trek’s SL OCLV Mountain Carbon frame, a high-modulus layup that delivers the stiffness serious XC racers crave while keeping the overall build as light and responsive as possible. The IsoStrut design integrates the RockShox SIDLuxe shock directly into the frame structure, acting as a structural component rather than a bolt-on afterthought. This approach resists torsional flex, maximises power transfer through the drivetrain, and ensures that every watt you put into the pedals goes directly forward. With 80mm of rear travel, an increase over the first-generation Supercaliber’s 60mm, the bike now handles modern XC course demands with more confidence and compliance without sacrificing its hallmark climbing efficiency. Sag can be dialled in anywhere between 15 and 35 percent, with Trek recommending 25 percent as the sweet spot for a balanced mix of pedalling efficiency and suspension response.Up front, the RockShox SID fork with DebonAir spring and Rush RL damper contributes 110mm of plush, controlled travel that keeps the front wheel tracking through roots and rocks with confidence. Both the fork and rear shock are operated via the RockShox Twistloc remote lockout, allowing you to firm up the platform in an instant on sustained climbs and open it back up as the trail gets technical. The revised second-generation geometry, featuring a 67.5-degree head angle, a longer reach, a steeper effective seat tube angle, and a 435mm chainstay, translates to a bike that feels planted and composed on descents while remaining aggressive and efficient on the climbs. Riders who explored the
Enduroplanet cross-country mountain bike range will find the Supercaliber SL 9.7 GX AXS Gen 2 sits firmly at the performance end of the XC spectrum, bridging the gap between trail versatility and outright race focus.SRAM’s GX Eagle AXS T-Type wireless electronic drivetrain handles all 12 speeds with crisp, reliable precision. The T-Type system’s improved chain retention and consistent shifting performance mean you can focus entirely on output rather than worrying about missed shifts or dropped chains mid-race. Stopping power is handled by SRAM Motive Bronze Stealth 4-piston hydraulic disc brakes, offering the bite and modulation needed on steep XC descents without adding unnecessary weight. The Bontrager Kovee Comp 25 tubeless-ready wheelset paired with Maxxis Rekon Race 29×2.40″ tyres rounds out the package, delivering the rolling speed and cornering grip that fast XC trails demand. As noted in a detailed review of the Trek Supercaliber Gen 2 on
Escape Collective’s 2024 Trek Supercaliber review, the bike is light, pedals extremely efficiently, and the handling is spot-on, making it one of the most compelling cross-country builds available at this level.
