endorphin 27.5:Block Font


**frames and full builds start at $1,399: CONTACT for the best pricing $$$, guaranteed!**

the endorphin has been on trails since 2009, and has been fighting way above its weight class the entire time. ask any of knolly’s factory feam riders, this bike just flat out rips. knolly has 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.
