Its SLR Mountain Carbon frame is as light as it is meticulous, with a high modulus lay-up that gives you all the stiffness you crave and none of the weight. It’s equipped with a 110 mm fork and 80 mm IsoStrut shock with Flight Attendant tech that delivers free speed with non-stop suspension adjustments as you ride.

You want to sprint up climbs and hammer to the finish, and let your bike do the thinking for you with 110 mm front and 80 mm of IsoStrut rear suspension with RockShox Flight Attendant. From wheels to cockpit, you crave carbon and you want the most meticulous high-mod carbon lay-up we offer on a mountain bike.

The tech you get - A featherweight, high-modulus SLR OCLV Mountain Carbon frame with modern XC geometry. 110 mm of front suspension from a RockShox SID SL Ultimate fork with DebonAir spring and Charger Race Day damper, and 80mm of IsoStrut rear suspension from a RockShox SIDLuxe shock – all with Flight Attendant tech.
