Trek Supercaliber SLR 9.8 XT Di2 Gen 2

Supercaliber SLR 9.8 is an ultralight XC mountain bike that's ready to lay down rubber on race day. Its SLR Mountain Carbon frame is as light as it is meticulous, with a high modulus layup that gives you all the stiffness you crave, and none of the weight. XC courses get rowdier every year, so it's equipped with a 110mm fork and 80mm of IsoStrut rear suspension to smooth your roll without kicking pedaling efficiency to the wind. It's all topped off with carbon wheels, a carbon cockpit, and ultra-smooth and fast shifting from a 12-speed Shimano XT Di2 wireless drivetrain.

• You get a featherweight ride decked out with speed saving upgrades, like Shimano's new, robust, yet lightweight XT Di2 wireless drivetrain, carbon wheels, and a Fox Factory 34 SL step-cast fork
• You get a 110mm fork and 80mm of IsoStrut rear suspension that partners with slacker, capable geometry for handling the roots and rocks of modern XC courses
• You don't have to compromise stiffness for weight savings thanks to the SLR OCLV Mountain Carbon frame that's intensely light, stiff, and responsive
• IsoStrut gives you tunable, damped suspension without missing out on efficiency for hammering up climbs at top speed
• Pivotless seat stays save on weight and actively bend to help soak up trail chatter
