THE TRAIL SNIPER.

The Endorphin has been on trails since 2009, and has been fighting way above its weight class the entire time. Ask any one of our Factory Team riders, this bike just flat out rips. We’ve always used the term ‘trail bike’ fairly loosely when it comes to the Endorphin and its capabilities, and version 3.0 is no exception. Cutting edge geometry and 130mm travel provided by our proprietary Fourby4 linkage system, this new Endorphin will dominate your local Enduro race, and the 70 mile out-of-bounds epic you have planned the following weekend.

When you review the geometry and specs tab(one click to the right) you will notice that our priority was to keep the Endorphin a fast and snappy ripper of a bike, regardless of wheel sizes growing in our industry. The numbers don’t lie, this bike is still low and slack, and is ready to do damage at your next dual slalom race.

The bells and whistles keep piling on as the Knolly lineup evolves each year: 

- 27.5 wheels
- 130mm travel
- Traction maximized by Knolly's own Fourby4 suspension system
- 6066 series alloy frameset is extensively hydroformed to maximize strength to weight ratio
- Dual ring compatible - provides superior set-up versatility
- Internal & external cable routing
- Main pivots rotate on highest quality angular contact catridge bearings
- Low stress pivot locations rotate on long lasting IGUS bushings
- 12x142 rear axle spacing
- Threaded BB for creak-free riding and simple installation
- ISCG05 tabs are removeable and replaceable
- Knolly's custom 'black ti' pivot fasteners keep things tight and classy
- Bottle mounts in a location that is actually useable
- Post Mount rear brake standard
- Massive Knolly tire clearance, as usual
