The latest version of the Knolly Endorphin has fully embraced the 27.5” wheel platform. Geometry was readjusted with priorities placed on keeping the fast, nimble and competence of previous models Knolly is known for. It is low, slack and capable of tearing up an enduro or dual slalom course one day, then providing the efficiency and all-day comfort for a high mileage weekend adventure the next. Patented Four by 4 Linkage is an extremely rigid design providing 130mm of travel with great pedaling dynamics, traction, and tracking capabilities. It also gifts the frame with clearance for large volume tires and access to the rear shock for easy set up and maintenance. Beautifully constructed with a highly hydroformed aluminum tube set.
The professionals here at Jenson have expertly outfitted the Endorphin with a host of capable components to take your riding to the next level. A SRAM GX Eagle 12-speed drivetrain delivers the gear range you’ve been looking for to tackle the climbs and mash downhills. Fox suspension provides a plush ride through the chop while soaking up the big hits with ease. Race Face Turbine wheels spin fast and smooth on sealed bearings while Schwalbe Han Dampf grip hard in a variety of conditions. A Race Face dropper post lets you get the saddle out of the way so you can attack technical terrain with confidence. When it comes time to slow things down, Shimano SLX disc brakes get the job done with authority.
Pink Bike - ”Knolly's bikes are famously adept technical climbers. In fact, this is one of the few bikes that can rival a good 29er when it comes to sniffing out any and all available traction.” - Mike Levy
