Trek / Cross Country Mountain Bikes
Superfly 32 SLR 9.6 is our fastest and most capable XC race bike ever, combining the rollover and traction advantages of 32˝ wheels with race-tuned full suspension. Its lightweight SLR OCLV Mountain Carbon frame delivers efficient pedaling and 110mm of rear travel, while a 120mm RockShox Reba Gold fork helps smooth rough courses and reduce fatigue. Bontrager Kovee Comp wheels and a SRAM Eagle 90 transmission round out a build that's ready to carry speed deeper into every race.
