While wholeheartedly Knolly in quality, design and application, the Endorphin features a substantially lightened frame from our previous offerings.

With 140mm (5.5") of rear travel, the ENDORPHIN is designed to be mated with the huge range of 130-160mm (5" - 6") forks currently on the market. Featuring a frame weight of around 7 pounds, the ENDORPHIN will make short work of technical XC trails, ledgy desert riding and long mountain climbs.

The ENDORPHIN shares many of the characteristics of our other full suspension frames, including full length seat tubes, superior handling, great tire clearance, a low suspension leverage ratio and a new version of our Four by 4 Linkage™ designed for a much lighter weight frame. And while the ENDORPHIN is definitely slimmed down compared to our longer travel frames, it's no wuss. Featuring a burly 31.6mm seat tube, full thickness replaceable dropouts, and impressive lateral rigidity the ENDORPHIN is the high that keeps on going.

With both air and coil shock options, a full range of sizes to fit riders from 5' and up, and flexible build kits available, the ENDORPHIN is set to carve it up no matter where you find your singletrack.
