Orbea Rallon M20 Mountain Bike 2022
Devised to perform at the highest echelons of enduro racing, the Orbea Rallon M20 Mountain Bike features an all-new, feature-packed design with more than a few tricks up its sleeve. A high-energy ride for demanding riders, the latest edition of the Rallon brings with it a previously unseen level of versatility. Whether roosting berms and seeking out gaps in the park or shaving seconds between the tape, the lightweight, monocoque carbon frame sees increased standover and progressive, stable geometry to see you ride at peak performance.
Enduro racing is a different beast now than at its inception, and the Rallon has evolved to meet these ever-changing needs. A degree of compliance limits fatigue on longer runs and enhances tracking through rough terrain, while integrated LOCKR frame storage offers enough room for a tube, tyre levers and CO2. The main pivot houses a cleverly hidden tool to assist with any mechanical snags, and a bottle opener on the axle assists with cracking open any post-ride beverages.
Although sporting a true enduro pedigree, the Rallon cranks up the fun factor for those seeking good times in the park. Included is a shock extender that allows for the fast-rolling 29” rear wheel to be exchanged for a more nimble 27.5” equivalent, boosting manoeuvrability for when steeze is prioritised over speed. Matching the burly intentions of the frame is the robust FOX 38 Float Performance fork, which delivers 170mm of plush suspension travel for rowdy riding. The 160mm of rear suspension is controlled by an exceptionally supple FOX Float X Performance shock, which features a lockout to boost climbing efficiency. A 12-speed Shimano groupset and M6120 four-piston brakes boost control over the bike, and a classic Maxxis Assegai front and Minion DHR II rear tyre combination delivers mind-boggling levels of traction across a range of surfaces.
