OCLV Mountain Carbon
Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.
E2 tapered head tube
E2 tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the stiffness of a full 1.5" system without the added weight.
Roll wrap seat tube cluster
Our exclusive one-piece, solid-construction seat tube provides the ideal combination of vertical compliance and lateral stiffness needed for the demands of mountain bike racing.
A more robust and confidence-inspiring rear thru axle, about 35% stiffer than an open-dropout design. And now, a thru-axle wheel change is actually quick and easy.
A 15mm front thru axle makes steering more precise for more control, and the quick-release feature makes wheel removal easy.
The gold standard for smooth, stable riding. Bigger wheels carry more momentum, roll over obstacles more easily, and offer greater stability and more traction than smaller options.
A 10-speed cassette and 2-ring crankset deliver a full range of usable gears, with less weight and easier, smoother gear shifting.
Balanced post mount brake
The brake calliper serves as a structural part of the frame, anchored between the chainstay and seatstay. It reduces weight by eliminating the need for a chainstay/seatstay brace.
CTD gives you three suspension-adjustment options: Climb, Trail, or Descend. It’s a simple, intuitive, high-performance system available on selected Fox shocks and forks.
Closed convert dropouts
Hardtails offer the robust performance of a closed through-axle system with the convenience of a system that can accept 142x12 or 135x5 rear spacing.
Fully integrated head tube
A fully integrated head tube eliminates the need for headset cups, reducing overall weight without sacrificing performance.
Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability.
Hydraulic disc brakes
Hydraulic disc brakes offer the absolute strongest stopping power even in wet and muddy conditions.
Internal Control Routing
Gear shift, brake, and lockout cables are routed through the frame for the lightest, cleanest, quietest MTB cable management system.
Kashima Coat fork
Kashima Coat metal finish on the fork stanchions reduces friction, for quicker suspension response and improved durability.
Removable Carbon Armor
Removable shield protects your OCLV Mountain Carbon frame, and you can take it off it when it’s time to get lean and fast.
