Endorphin GX MX29
Knolly
Enduro
Endorphin GX MX29 is an alloy enduro mountain bike (2024), by Knolly, part of the Endorphin family. It suits riders who want a more active, performance-leaning off-road feel, with a setup that gives you a sporty, active riding position, and is aimed at more technical trails and rougher terrain. Its profile is strongest in areas like strong climbing friendliness for sustained uphill riding and capable suspension support for rougher terrain. Compared with more specialized alternatives, the compromise is a firmer ride feel than comfort-first options and less emphasis on outright speed than speed-focused builds.
