Trek Supercaliber SL 9.6 Gen 2 2024 – Dark Prismatic | Carbon XC Speed with Show-Stopping Colour

Not every great XC race bike needs to look understated. The Trek Supercaliber SL 9.6 Gen 2 2024 in Dark Prismatic brings together all the race-proven engineering of the Supercaliber platform with a finish that genuinely stands out on the start line. Dark Prismatic is one of Trek’s most visually striking paint options — a deep, shifting iridescent finish that shimmers with colour as the light changes, giving this carbon XC machine a premium, eye-catching look that matches its exceptional performance.

Underneath that stunning finish is a bike that has been completely overhauled from its predecessor. The Gen 2 Supercaliber arrives with a fully redesigned frame, updated geometry, an increase in rear suspension travel, a new generation of IsoStrut, and a dropper post included as standard. Reviewers who have tested it have called it one of the best XC bikes they have ever ridden — and for good reason. Every element of this bike has been designed to make you faster, fresher, and more in control across every type of cross-country terrain.

A Completely New SL OCLV Mountain Carbon Frame

The Gen 2 Supercaliber SL 9.6 is built around an all-new SL OCLV Mountain Carbon frame that represents a significant step forward from the original Supercaliber design. Trek’s OCLV — Optimum Compaction, Low Void — carbon manufacturing process ensures exceptional consistency and structural integrity throughout every fibre layer, delivering a frame that is simultaneously light, stiff, and vibration-damping. The Gen 2 frame saves an average of 200g compared to its predecessor depending on size, bringing it to a highly competitive weight for the SL carbon category.

The Gen 2 also introduces a significantly slacker 67.5-degree head angle, compared to the 69-degree angle on the original model. This geometry update transforms how the bike handles on technical terrain — more confident on descents, more planted through fast corners, and more capable on the increasingly technical race courses that define modern XC competition. Reach and seat angle have also been refined, and the bottom bracket height has been raised 10mm to reflect the increased rear suspension travel and to improve anti-squat characteristics for better pedalling efficiency under power.

Internal cable routing runs throughout the frame via Trek’s Control Freak guide tube system, protecting cables and housing from trail debris and simplifying long-term maintenance. The frame also carries two carbon bottle cages as standard — a welcome practical touch for longer race efforts and trail rides alike.

IsoStrut Gen 2 Rear Suspension — 80mm of Pivotless, Efficient Travel

The heart of the Supercaliber SL 9.6 is Trek’s IsoStrut rear suspension system, now in its second generation and more refined than ever. IsoStrut replaces conventional pivot-and-linkage hardware with a pivotless seat stay design, where the seat stays actively flex to deliver approximately 80mm of rear wheel travel through an integrated RockShox SIDLuxe-based shock housed within a 38mm alloy IsoStrut tube.

This design approach results in significantly less lateral flex than conventional full-suspension designs, reduced maintenance requirements, and a lower overall weight. The system is fully tuneable like a standard rear shock, and the two-position remote damper — activated at the handlebar — allows instant switching between active trail suspension and a firmer, more efficient climb mode. Trek’s own performance research engineers have demonstrated that the Gen 2 Supercaliber is not only more comfortable than its predecessor, but measurably more efficient than a comparable hardtail — a result that challenges conventional assumptions about suspension and efficiency in XC racing.

The pivotless seat stays are themselves an active part of the suspension system, bending to soak up trail chatter and micro-impacts that would otherwise sap rider energy on longer efforts.

RockShox Recon Gold RL Fork — 110mm Front Suspension

Up front, the Supercaliber SL 9.6 is fitted with the RockShox Recon Gold RL fork, delivering 110mm of travel via a DebonAir spring and Motion Control damper. The DebonAir air spring provides a supple, responsive feel from the very first millimetre of travel — critical for maintaining traction and control over the sharp, high-frequency impacts found on rocky XC trails. The Motion Control damper provides consistent, adjustable damping, while the manual lockout gives you firm, efficient pedalling when the terrain allows. The tapered steerer and 15mm Maxle Stealth thru-axle ensure precise, stable steering response throughout.

Shimano SLX / Deore 12-Speed Drivetrain — Wide-Range and Ready to Work

The drivetrain on the Supercaliber SL 9.6 2024 is a Shimano combination of SLX M7100 rear derailleur and Deore M6100 12-speed shifters and cassette. The Deore M6100 cassette runs a 10-51 tooth spread — a genuinely enormous gear range that covers the steepest technical climbs and the fastest flat sprints with equal capability. Shimano’s Hyperglide+ chain and cassette interface delivers smooth, consistent shifts under load, and the mechanical actuation means no charging, no wireless pairing, and no electronic gremlins on race day.

The Shimano MT512 crank runs a 32-tooth chainring with a 55mm chainline, optimised for chain retention and smooth power delivery across the full cassette range.

Bontrager Kovee Comp 23 Tubeless Ready Wheels and Dropper Post as Standard

The 2024 Supercaliber SL 9.6 rolls on Bontrager Kovee Comp 23 Tubeless Ready wheels — a solid, dependable wheelset that comes set up tubeless-ready out of the box, complete with Bontrager TLR rim strips, valve stems, and sealant included with the bike. Paired with Bontrager Sainte-Anne RSL XR 29×2.40″ tyres, the rolling package delivers excellent traction and trail confidence across a wide variety of surfaces.

A Bontrager Line dropper post is included as standard — a meaningful commitment from Trek that acknowledges that modern XC trails require the ability to drop the saddle quickly for technical descents. Shimano hydraulic disc brakes provide reliable, all-conditions stopping power to round out a bike that is genuinely complete and race-ready from the first ride.
