The Orbea Oiz M-PRO 2027 bikewe’re introducing atEscaparedefines the concept of a Cross Country and Marathon bike, combining extreme lightness, pedaling efficiency, and surprising capability on technical terrain. With a completely redesigned frame following three years of development, the Oiz has evolved toward modern XC, where speed depends not only on climbing fast but also on descending with control and maintaining your pace on any Terreno.
COMPETITION-LEVEL PERFORMANCE
Optimized Stiffness
Three years of work have shaped a completely new frame, with a clear goal: to improve every aspect of performance to build one of the most capable bikes on the market today. Development has focused on a critical balance in modern XC: increasing stiffness without sacrificing weight.
The new rocker arm is one of the keys to the new Oiz: it reduces its size while increasing its stiffness. The material has evolved from carbon to forged aluminum, and—along with strategic cutouts in the link—reduces its weight by about 30% compared to the previous model. Added to this is a new bridge that supports and reinforces the seatstays while keeping the rear triangle perfectly aligned under load.
Orbea has optimized the frame’s geometry by eliminating abrupt transitions, which promotes more efficient carbon compaction and reduces the use of epoxy resin, thereby improving the stiffness-to-weight ratio. The top tube design, featuring structural fins, increases stiffness.
The chainstays and seatstays have been carefully engineered to provide maximum torsional stiffness without adding unnecessary weight, thereby increasing stability on technical terrain.
Finally, the Powerspine, which runs along the lower section of the frame from the Headset to the bottom bracket, optimizes power transfer—especially during explosive efforts like sprints—delivering superior performance on the bike.
A stiffer frame saves watts on climbs by optimizing power transfer and ensuring that every effort translates into actual forward momentum. On descents, reducing unwanted movement provides greater precision in line choice, allowing you to ride with greater confidence and control. Additionally, improved suspension performance—thanks to minimized torsion at the main pivot point—results in more effective shock absorption, smoother operation, and total control in the most demanding conditions.
Suspension Developed for Competition
The Oiz establishes itself as a 120 mm platform both front and rear, fully adapted to modern XC. The geometry is optimized for this travel, though a 130 mm fork can be selected for added capacity.
The kinematics maintain a regressive approach, prioritizing support in the first part of the travel. This improves pedaling efficiency by reducing unwanted sag and minimizing suspension sway in the open position. The use of a low-volume shock allows for adequate progressiveness in the final portion of the travel and prevents bottoming out. The result is a suspension system that delivers exceptionally capable performance, with a well-balanced blend of efficiency and shock absorption.
The geometry has also been refined with subtle yet effective adjustments.
- The chainstays are shortened from 432 mm to 430 mm, enhancing responsiveness and acceleration, especially during explosive efforts such as sprints or standing climbs.
- The seat tube is now more vertical, offering a more forward riding position that improves power transfer and front-wheel traction on the steepest climbs.
- The head tube angle is slightly relaxed, going from 67° to 66.8°, which provides extra stability and control at high speeds.
The patented I-Line technology runs along the frame’s top tube to the rear shock, eliminating bends in the cabling, which increases durability and reduces friction for smoother, more efficient operation. In turn, the Squidlock system consolidates control of the dropper post and suspension into just two levers, allowing you to access the three suspension positions without taking your hand off the handlebars. Compact, reliable, and compatible with Shimano and SRAM brake calipers, as well as multiple suspension systems, Squidlock guarantees total control in any situation.
Uncompromising Lightness
The construction of the new Oiz eliminates any element that does not directly contribute to performance, making it one of the lightest frames in the XC category.
At the top of the lineup, OMX carbon represents the ultimate in lightness and stiffness for competition.
