Orbea Oiz 29 M50 Bike 2018

Orbea Oiz 29 M50 Bike 2018

The Orbea Oiz was designed from the ground up to be as capable and efficient as possible. Originally built around the 26” wheel platform, the Oiz has adapted Orbea’s BWC (Big Wheel Concept) by offering 27.5” (650b) models in S/M/L. This method considers the rider’s height and riding style when sizing the bike - avoiding improperly sizing a bike in an attempt to compensate for an ill-matched wheel size.

At the heart of the Orbea Oiz is the Advanced Dynamics development process - a simulation program that allows the engineers to meticulously study how the frame and suspension will perform depending on rider size and exerted forces. This virtual testing ground allows Orbea is finely tune their frame geometry and suspension platform before ever creating a single prototype bike. The Oiz’s XC geometry was devised for going fast, providing the proper head tube angle to allow for precise steering through technical terrain while also remaining stable after picking up speed. Additionally, the seat tube angle is strategically positioned to provide the best leverage when climbing steep and rugged terrain.

As the whole point of suspension on a mountain bike is to absorb the rough stuff and keep your wheels in contact with the ground, the Adavanced Dynamics Technology not only relieves the rider of forces exerted by the trail, but also provides better traction and control through technical and bumpy terrain. In an effort to reduce friction and increase efficiency, the Oiz uses Sealed Ball Bearings rather than bushings. This, along with the optimized leverage curve provided by the Diamond Link, allows the suspension system to provide excellent pedaling efficiency and small bump compliance. To further improve the overall suspension performance, Orbea includes a bearing at the rear shock mount, which is partly what sets Obrea suspension system apart from the rest - allowing the suspension to move freely while keeping the bike stiff and without adding unnecessary weight.

The Oiz M50 Build features a perfect combination of the ultra-reliable, smooth shifting performance of a Shimano SLX/XT drivetrain with the fiercely capable Oiz OMP frameset. Mount up a Fox 32 Float SC Factory 100 FIT4 Remote-Adj QR15x110 Kashima to the front and a Float DPS Factory 3-Position to the rear, then set it atop a set of Mavic Crossmax Elite TL 6-Bolt, and you’ve got yourself a weekend race-assassin.
