All Mountain 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.
The Endorphin is ready for pretty much anything all-mtn that you can throw at it!

What size seatpost does my bike take?
All Knolly frames take a 31.6mm seatpost.
What size quick release seat collar do I need for my Knolly frame?
The seat collar size is 35mm and we recommend the Chromag seat collar which can be purchased with your Knolly Frame.
How much seatpost insertion do I need?
Knolly recommends a minimum of 4 inches or 100mm of post insertion into the frame.
How should I setup the rear air shock sag?
Start by putting your body weight in pounds into the main air chamber. So if you weigh 170 pounds put 170 psi into the rear shocks main chamber. Get on the bike with all your riding gear, including water in the Dakine Pack, now check suspension sag. To do this, pull the little O-ring up on the shock shaft; now get off the bike gingerly as to not upset that measurement. Once off the bike, measure how much shock shaft is exposed above the O-ring. For proper setup you should measure about 25-30% of sag from total stroke.
How should I set up my rear shock? How should I torque my frames' bolts?
Please see the Shock Settings and Torque Specs links above for these values.
You specify certain travel forks for each model, what if I run a fork with more travel or a longer axle to crown measurement?
By running a longer than recommended fork, it will slacken the angles and increase the standover. A general rule of thumb is for every inch of travel change equates to a degree of angle change. In ablockquoteition you may void your warranty by using the wrong fork.
