If you shred singletrack like it's your full-time job, it's time to check out Trek's unbelievable Fuel EX 9.9. Its Trek OCLV Mountain Carbon frame uses off road-specific carbon, so it's light and also super tough and resistant to trail impacts. This dream-come-true is equipped with the best there is: a full SRAM 10-speed XX parts group with carbon XX cranks and carbon Bonty Race XXX Lite specs throughout. And at just 1,560 grams, the DT Swiss Tricon wheels are sick-light and provide DT's renowned durability. And no Fuel would be complete without 120mm of custom front and rear Fox suspension along with Trek's winning ABP, EVO and Full Floater technologies backing you up. One last thing: on Trek's scale, this rig weighs just 22 pounds! Amazing.
