Description
A fun and fast option that ticks all the boxes for riders seeking burly cross-country performance, the Orbea OIZ M20 TR Mountain Bike features 120mm of supple, traction-rich suspension to mould to the terrain. With its TR designation, this model features a slacker head angle and 20mm more suspension than its more race-oriented stablemate, injecting confidence and versatility into every ride. Constructed from OMR carbon fibre, this frame is light and stiff, utilising an aluminium rocker link to drive the unique Fiber Link suspension design.
Fast and performance-oriented, the 29” DT Swiss X-1900 Spline wheels provide stability and speed through rough terrain. SRAM take care of shifting duties, with their 12-speed GX drivetrain providing proven, reliable gear changes across the wide 10-50t cassette. Maxxis tyres deliver grip on hardpack terrain, and an Orbea OC MC20 dropper post boosts confidence when descending tricky trails. The Orbea Squidlock system neatly houses a lockout and dropper remote to maintain a sleek aesthetic, and FOX Performance suspension units deliver excellent grip and bump absorption.
