The Fuel EX 9.0 presents Trek's trail bike specific geometry in a carbon frame, transforming the EX from a great trail bike into a light weight, nimble, full suspension singletrack masterpiece that's ready to take on the XC race circuit with style.

Tubing. Trek’s high-performance carbon fibre, OCLV Black, uses a mix of medium and high modulus content. Multi-piece Construction Method (OCLV MCM™) optimizes each section of the frame for specific performance and ride characteristics.
Proprietary Optimum Compaction Low Void (OCLV) carbon fibre technology ensures consistent performance, quality, and reliability.
Suspension. ABP (Active Braking Pivot) gives the best suspension performance at high speed braking.
Full Floater design places shock mounts on two moving linkages for a precision tuned system that has initial small bump compliance, great mid-stroke control and seemingly bottomless travel.
One-piece EVO Link adds stiffness and reduces weight.
Aluminum and magnesium links. R1i system that builds on R1 system of optimized single pivot rocker link and category-specific geometry. R1i is R1 plus ABP, Full Floater and EVO Link technologies.
Travel. 130mm front wheel and 120mm rear wheel travel.
