Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2

The Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2 is a purpose-built cross-country race machine that bridges the gap between hardtail efficiency and full-suspension compliance. Draped in a striking Navy Blue finish, it is engineered for riders who demand podium-ready performance on the most demanding XC courses in the world.

Who Is the Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2 Built For?

This bike is built for competitive cross-country racers and high-performance XC enthusiasts who are not willing to sacrifice pedalling efficiency for suspension compliance. It suits riders who regularly tackle technical climbs, rocky singletrack, and rowdy descents in a race or aggressive trail context, and who want a bike proven at the elite level. Available in sizes Small through X-Large, it fits riders from 155 cm to 195 cm.

Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2: Race-Proven Performance on Every Terrain

At the heart of the Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2 is Trek’s proprietary IsoStrut suspension system, a design that integrates directly into the SLR OCLV Mountain Carbon frame. Unlike conventional full-suspension layouts, the IsoStrut uses a RockShox SIDLuxe shock built directly into the rear triangle, delivering 80mm of rear wheel travel with virtually no pedalling inefficiency. Trek’s engineers relocated the main pivot 10mm upward compared to the first generation, resulting in a flatter leverage ratio that dramatically improves small-bump sensitivity. The result is a bike that absorbs trail chatter and root strikes with a composure far beyond what 80mm figures suggest, while still returning every watt of pedalling effort directly to the rear wheel. This is a bike that climbs like a hardtail and descends with the composure of a full-suspension rig.

The Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2 pairs that suspension pedigree with a component package that leaves nothing on the table. Up front, 110mm of travel from the RockShox SID Select+ fork with a DebonAir spring and Charger Race Day damper gives you plush, controlled front-end feel with a dual remote lockout for instant on-the-fly suspension management. The SRAM X0 Eagle AXS T-Type drivetrain operates on a fully wireless electronic platform, offering buttery-smooth shifting under full sprint loads without the weight or complexity of a direct-mount cable system. Paired with a 10-52T cassette and a 30T chainring, the gearing range handles the steepest climbs and fastest fire-road sprints with equal confidence. The SRAM Level Silver Stealth 4-piston hydraulic brakes deliver powerful, consistent modulation even on long, loose descents. You can explore the full Trek XC range available at Enduroplanet, South Africa’s dedicated cycling destination.

Geometry on the Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2 has been updated for Gen 2 with a longer reach and a slightly slacker head tube angle of 67.5 degrees to inspire confidence on technical descents without blunting the snappy, efficient climbing character that defines XC racing geometry. Chainstay length is a consistent 435mm across all sizes for predictable cornering feel, while a 109mm trail figure keeps the steering precise and responsive. The one-piece Bontrager RSL Integrated carbon bar and stem combination shaves critical grams from the cockpit while adding stiffness exactly where power transfer demands it. Bontrager Kovee Elite 30 carbon wheels with a 29mm inner width and Rapid Drive 108-engagement rear hub round out a build that is relentlessly fast and technically complete. Dressed in Navy Blue, this is a bike that looks every bit as sharp as it rides.

5 Reasons You’ll Want the Trek Supercaliber SLR 9.8 X0 AXS T-Type Gen 2

• Hardtail efficiency, full-suspension control: Trek’s IsoStrut technology delivers 80mm of rear travel that adds compliance and grip without robbing a single watt of pedalling power, giving you the best of both worlds in a single lightweight package.
• Wireless precision under race pressure: The SRAM X0 Eagle AXS T-Type electronic drivetrain shifts flawlessly under maximum load, so you can stay in full sprint mode through gear changes without hesitation or chain drop risk.
• Weight that gives you an edge: At just 11.28 kg in a Medium build, the SLR OCLV Mountain Carbon frame and carbon component package put you at a serious weight advantage on every climb, every start line, and every timed segment.
• A cockpit built for race-day confidence: The one-piece Bontrager RSL Integrated carbon handlebar and stem combination reduces weight, increases stiffness, and keeps the front end tidy and aerodynamic, so you stay focused on the trail ahead rather than managing flex.
• Carbon wheels that roll faster and last longer: Bontrager Kovee Elite 30 OCLV Mountain Carbon wheels with a Rapid Drive 108-engagement hub and tubeless-ready rims give you rapid power transfer, reduced rotating mass, and the durability to handle the rowdiest XC courses season after season.
