2025 Orbea Oiz M21 (Demo | OD260703)

About This Bike

This 2025 Orbea Oiz M21 in Seaweed Carbon View/Spaceship Green is a high-performance carbon cross-country bike built for riders who want fast acceleration, efficient climbing, and added control on technical trails. The large OMR carbon frame uses 120mm of front and rear travel with 29-inch wheels, creating a modern race-oriented platform that can handle more demanding terrain than a traditional short-travel XC bike. This demo bike remains in the original 2025 M21 factory specification with no component substitutions.

Condition Notes:

• Scratches on derailleur
• Scratches on right side seat stay
• Scratches on both crank arms
• Scratches on both fork decals
• Scratches on rear brake lever
• Small chips in clearcoat on left side of top tube near shock mount
• Scratches on left side of rear triangle near axle

The Oiz M21 uses Orbea’s OMR carbon construction for both the front and rear triangles. A FiberLink upper linkage and Advanced Dynamics UFO flexstay suspension layout manage 120mm of rear-wheel travel while limiting unnecessary hardware. This design helps preserve the bike’s responsive pedaling feel and low overall weight while delivering traction and control across rough surfaces.

Front suspension is handled by a RockShox SID Select fork with 120mm of travel, a DebonAir+ spring, RL damper, and 35mm stanchions. The fork combines steering accuracy with efficient weight, fitting the Oiz’s cross-country purpose. A RockShox SIDLuxe Select+ rear shock uses a 190 x 45mm configuration and works with the frame’s custom suspension kinematics. Both units are controlled by the OC Squidlock MP11 three-position remote lockout.

The factory SRAM GX Eagle mechanical drivetrain provides 12-speed shifting through a GX Eagle shifter and rear derailleur. An XG-1275 cassette supplies a 10-52-tooth range, giving the rider low climbing gears and useful top-end speed. The stock SRAM GX Eagle alloy DUB crankset uses a 32-tooth chainring and runs through a threaded SRAM DUB bottom bracket for straightforward maintenance and dependable power transfer.

Shimano Deore M6100 two-piston hydraulic brakes deliver controlled, consistent stopping performance with Shimano rotors. This lightweight braking package is well matched to cross-country and trail use, offering smooth modulation for technical sections without adding excessive weight. Cosmetic wear on the rear lever is documented in the condition notes above.

OQUO Mountain Performance MP28Pro alloy wheels use a 28mm internal rim width with Boost hub spacing and an XD driver. Maxxis Rekon Race tires measure 29 x 2.4 inches and feature EXO casing, 120 TPI construction, and tubeless-ready compatibility. Together, the wheel and tire system prioritizes rolling speed while maintaining useful support and traction on loose or uneven trails.

The cockpit features an OC Mountain Performance MP30 handlebar with a 760mm width and an OC Mountain Performance MP21 stem with a 6-degree drop. Orbea’s SIC routing system conceals the cables and hoses through the headset, while the Spin Block rotation limiter helps protect the frame from excessive handlebar movement. OC lock-on grips complete the clean, integrated setup.

An OC Mountain Control MC22 dropper post allows the saddle to move quickly out of the way for steeper terrain and technical corners. Its remote is integrated with the Squidlock MP11 suspension control to reduce cockpit clutter. The fi’zi:k Vento Argo X5 saddle uses aluminum rails and a race-focused shape suitable for efficient seated pedaling.

Finished in Seaweed Carbon View/Spaceship Green, this large 2025 Oiz M21 combines distinctive styling with an efficient, carefully integrated component package. The OMR carbon frame, RockShox SID and SIDLuxe suspension, SRAM GX Eagle drivetrain, OQUO wheels, and remote controls make it a capable choice for racing, endurance riding, and fast trail days. Offered at $2,999 against a $4,999 MSRP, this demo bike delivers substantial value with all known cosmetic wear disclosed clearly above.
