GT's full XTR-equipped Marathon Team is a race machine that has been forged from years of winning. This full carbon rocket sports a stiff rear end for getting the hole shot and GT's renowned ID platform for super-efficient pedaling and plush, active suspension. Speaking of suspension, Fox gives you a race-wining package like the 3-pound, 120mm 32 RL fork and 100mm Float shock, both of which are custom tunable so you can dial them in for race day. The race-bred spec shows its teeth with a full XTR group, including tubeless wheels wrapped with Kenda rubber and feather-light, powerful brakes. A Thomson post and Ritchey carbon WCS bar further proves that this thoroughbred is built for speed.
