Trek Supercaliber SL 9.7 GX AXS T-Type Gen 2 2025 – Red Carbon Smoke | Wireless XC Racing with Full Carbon Build

The step between a race-capable XC bike and a genuinely race-winning one often comes down to drivetrain precision and cockpit quality. The Trek Supercaliber SL 9.7 GX AXS T-Type Gen 2 2025 in Red Carbon Smoke makes that step decisively — bringing Trek’s proven SL OCLV Mountain Carbon frame and IsoStrut suspension platform together with a fully wireless SRAM GX AXS 12-speed electronic transmission, a RockShox SID fork, Bontrager Kovee Comp 30 carbon wheels, and a full carbon cockpit into a complete, race-ready package that is loaded with technology from top to bottom.

Red Carbon Smoke is a bold, richly layered colourway — a deep red tone applied over a raw carbon-look base, creating a finish that shifts and shimmers in different lighting conditions. It is a striking, premium-looking colourway that brings real visual presence to a bike that already stands out for its specification and performance.

The Supercaliber SL 9.7 occupies a compelling position in Trek’s Gen 2 Supercaliber lineup — more capable and fully-featured than the entry-level 9.6, with a complete wireless SRAM drivetrain, carbon bar setup, and upgraded suspension components that transform the race-day experience without stepping to the very top of the range. For riders who want wireless shifting, a carbon cockpit, and carbon wheels in a complete XC race machine, this is where the Supercaliber SL genuinely comes into its own.

SL OCLV Mountain Carbon Frame — Gen 2 Race Geometry, Race-Grade Construction

The frame at the core of the Supercaliber SL 9.7 GX AXS is Trek’s SL OCLV Mountain Carbon — the same high-quality, lightweight carbon construction found across the Gen 2 Supercaliber SL range. OCLV (Optimum Compaction, Low Void) is Trek’s manufacturing standard for consistent, high-integrity carbon fibre construction, eliminating voids and inconsistencies that can compromise structural performance. The SL grade delivers a lightweight carbon lay-up that balances stiffness with enough compliance to damp vibration, keeping riders fresher and more comfortable across long race efforts and technical trail riding.

The Gen 2 frame brings a meaningfully slacker 67.5-degree head tube angle compared to the original Supercaliber, reflecting the reality of modern XC courses that are technical, rough, and demanding of genuine trail confidence. Reach and seat tube angle have been refined for a more powerful riding position, and bottom bracket height has been raised 10mm to improve anti-squat performance under pedalling load. Internal cable routing runs throughout the frame via guide tubes, protecting cables and housing and keeping the exterior of the bike clean and uncluttered. Chainstay protection moulding and 3M adhesive film on the underside of the downtube protect the frame from rock strikes and trail debris.

Two carbon bottle cage mounts are included inside the front triangle as standard — a practical addition for long race stages and extended training rides where on-bike hydration is non-negotiable.

IsoStrut Rear Suspension — 80mm of Pivotless, Proven Efficiency

The defining technology across the entire Supercaliber platform is Trek’s IsoStrut rear suspension system, and the Gen 2 iteration is the most refined version yet. IsoStrut replaces conventional pivot-and-linkage rear suspension hardware with a RockShox SIDLuxe-based shock integrated directly inside the frame structure, with the pivotless seat stays flexing actively to deliver approximately 80mm of rear wheel travel. The absence of traditional suspension hardware means significantly less lateral flex, lower maintenance requirements, and a lighter overall rear triangle than any comparable conventional full-suspension design.

Trek’s own performance research engineers have confirmed that the Gen 2 IsoStrut Supercaliber is measurably more efficient under pedalling load than a comparable hardtail — a result that continues to set the Supercaliber apart from every other XC full-suspension platform on the market. The two-position remote lockout damper, controlled from the handlebar, allows instant switching between an active suspension mode for rough terrain and a firm, locked climbing mode — without breaking riding position or losing race momentum.

RockShox SID Fork — 110mm of Race-Day Front Suspension

The Supercaliber SL 9.7 GX AXS steps up from the Recon Gold RL found on the 9.6 to the RockShox SID fork — one of the most respected XC suspension forks in the world, trusted by elite racers at the highest levels of the sport. The SID on the 9.7 features a DebonAir spring and Rush RL damper, delivering 110mm of smooth, supple, and well-controlled travel. The DebonAir spring’s progressive air volume curve provides excellent small-bump sensitivity at the start of the stroke — critical for traction on rough, technical terrain — while the Rush RL damper delivers consistent, low-friction damping throughout. The dual remote lockout allows instant transition from active to locked mode at the handlebar, and the 35mm stanchions provide enhanced stiffness and steering precision at the head tube. The Maxle Stealth thru-axle ensures secure, rattle-free wheel retention throughout.

SRAM GX AXS T-Type — Fully Wireless 12-Speed Electronic Transmission

The drivetrain that defines the Supercaliber SL 9.7 as a step above the mechanically-shifted 9.6 is the SRAM GX AXS T-Type — a fully wireless, 12-speed electronic transmission that brings cable-free precision shifting to a highly accessible price point within the wireless drivetrain category. T-Type denotes SRAM’s latest-generation derailleur interface and chain system, originally developed for the flagship XX and X0 AXS groupsets and now extended to GX, delivering the same direct-mount derailleur precision, superior chain retention, and smooth-shifting performance at a more accessible tier.

SRAM GX AXS eliminates every cable from the drivetrain — there is no cable tension to manage, no cable stretch to compensate for, and no mechanical adjustment required between rides. Shifts are executed instantly at the press of a wireless lever, with the same speed and precision regardless of whether you are pedalling hard on a climb or resting on a descent. The SRAM AXS ecosystem also allows shift mapping customisation and battery status monitoring via the AXS app, and the system includes a battery charger as standard. The wide-range cassette provides a comprehensive gear spread for every terrain type the XC course can present.

Bontrager Kovee Comp 30 Carbon Wheels and Full Carbon Cockpit

One of the most significant upgrades the Supercaliber SL 9.7 offers over the 9.6 is the wheelset — Bontrager Kovee Comp 30 OCLV Mountain Carbon wheels replace the alloy Kovee Comp 23 of the entry model. A 30mm internal width carbon wheelset is lighter, stiffer, and more responsive than its alloy equivalent, contributing to improved acceleration, better tyre support, and a noticeably more direct and energetic ride quality. The Rapid Drive 108 freehub engagement at the rear provides near-instant power pickup, and the tubeless-ready setup comes complete with Bontrager TLR rim strips, valve stems, and sealant included with the bike.

The cockpit is the Bontrager Line Pro OCLV Carbon handlebar — a lightweight, single-piece carbon bar with a 35mm clamp diameter that provides a stiff, direct connection between the rider’s hands and the front of the bike. Available in 720mm width for size Small and 750mm for Medium through XL, the carbon bar reduces weight at one of the most critical contact points on the bike and contributes to the overall carbon-everywhere build philosophy of the 9.7. SRAM Level Bronze 4-piston hydraulic disc brakes with 180mm front and 160mm rear CenterLine rotors deliver powerful, consistent, all-conditions stopping performance to complete the specification.
