Orbea OIZ M20 TR Mountain Bike 2022
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.
Highlights
- The OIZ TR takes a thoroughbred XC racing platform and adds bigger suspension, front and rear to create a super-fast and nimble character that is set to conquer any trail
- An OMR carbon frame delivers an excellent stiffness to weight ratio
- UFO rear suspension design reduces pivot points and combines with the Alloylink junction to deliver lateral stiffness, a composed action and low weight
- FOX i-line DPS Performance rear shock with 120mm of suspension offers plush performance
- FOX 32 Float SCPerformance fork sees 120mm of bump-eating suspension travel
- The geometry is aggressive and precise for maximum power transfer and rapid handling
- Fast-rolling 29” DT Swiss X-1900 Spline wheels are ideal for cross-country
- SRAM GX groupset provides proven crisp shifting and excellent chain retention
- Shimano M6100 hydraulic disc brakes are powerful and controllable through steep terrain
- A dropper post is added to improve speed on undulating terrain
