Spearfish C Deore 12 is our endurance and XC MTB made for the most challenging days on the bike, ranging from 12-hour races to bikepacking events. Its stiff carbon frame wastes no watts, and 120mm of Split Pivot rear suspension adds to the efficiency ethos with responsive pedaling performance, predictable braking, and excellent traction. A RockShox SID fork adds 120mm of trail-smoothing travel up front.

Spearfish’s on-bike cargo features make long days out easier, with capacity for two bottles (up to three on MD–XL frames), and your repair kit, plus top tube mounts for accessories like our EXP-R Series Trillium Top Tube Bag or a K-Edge computer mount. The Shimano Deore 12-speed group is a reliable workhorse that goes mile after mile without issue — just like you. Spearfish C Deore 12 is the carbon endurance and XC MTB for your most ambitious pursuits.
