Trail and All Mountain. Dominated and Defined.
The Endorphin defines all mountain riding: when something climbs, descends and just plain rails trails as competently as the Endorphin does, it can only be called the great all-rounder...
Perfectly suited for the wide range of 140-160mm forks on the market, and ready to rip trails from Fruita desert to Austin's rocks to Squamish's technical singletrack, this is Knolly's middle weight contender. The Endorphin is more than nimble enough to dance around the ring effortlessly but can easily handle a solid thrashing.
