Our version of a trail bike: low, slack, and built to rip.
Available Colours
Anodized Black

Day Glow Yellow
Blue
When your trail ride turns into an all-mountain epic.
Quick….Nimble….Stiff. Featuring the most aggressive geometry in the trail bike category, this Endorphin is built to rip. By shedding over a pound and basing geometry around a 150mm fork, this Endorphin is snappier than previous versions, and designed for all-day trail shredding.
The 2013 Endorphin is packed with features not usually found on a light weight trail bike including 12 x 142mm rear thru axle, dropper post cable routing, direct mount front derailleur, and ISCG tabs to boot. Our standard builds settle in at 26 pounds, with plenty of opportunity to go lighter.
From epic rides to enduro races, the Endorphin has the chops to get you down the hill with plenty of time for dinner and a couple cold ones.
