Orbea Oiz M PRO TR Mountain Bike 2021
The Orbea Oiz M PRO TR Mountain Bike takes a full carbon, cross country racing platform and an aggressive geometry and adds bigger suspension to result in a ride that’s ready to conquer any trail, no matter its technicality or severity.
OMX carbon is at the height of Orbea’s composite technology and is used for the front and rear frame triangles to elicit a lofty stiffness to weight ratio. A highly technical rear suspension design includes a super clean linkage arrangement to result in a lightweight configuration that collaborates with the FOX damping unit to progressively manage the biggest of hits with aplomb. A FOX 32 Float SC Factory suspension fork supplements the frame by adding its 120mm of travel to deliver composure across even the roughest of trails. The chassis possesses an aggressively tuned geometry that promotes reactive handling in the tightest of riding situations and places the rider powerfully over the pedals.
DT Swiss XR-1650 Spline wheels use robust but light 29” alloy rims that surge forward under power and maintain impetus over the most irregular of terrain. Driving these wheels is the slick and dependable Shimano XT and XTR gear partnership while stopping duties are taken care of by powerful and precise hydraulic disc brakes.
A dropper post is added to give heightened levels of control when thundering down steep escarpments.
