Orbea Alma M-PRO 29" Mountain Bike 2021
By utilising Orbea’s highest-end OMX carbon technology, the Orbea Alma M-PRO 29" Mountain Bike delivers a responsive and ultra-fast ride to elevate your cross-country performance. The performance-orientated specification sees the M-PRO equipped with the high-end 100m FOX 32 Float SC Factory fork and Shimano XT groupset, making it race-ready right out the box. The OMX carbon construction is the result of thousands of hours of lab and field testing and is of the highest quality. Ultralight and responsive, the frame provides razor-sharp handling to excel on modern cross-country courses.
Built for precision the Alma geometry maximises efficiency, with its angles encouraging an aggressive position. Despite its race-focused geometry, comfort is retained thanks to compliant carbon seatstays, ensuring the frame is as comfortable as it is fast. Internal routing keeps the cables out of harm’s way and keeps the frame sleek, and the Acros Block Lock headset prevents the fork impacting the frame in the event of a crash.
With a cross-country focused Step Cast design, the FOX 32 Factory fork features the FIT4 damper with a handlebar-mounted remote lockout. The DT Swiss X 1900 Spline wheelset ensures fast acceleration thanks to the DT Swiss 370 hubs, and uses 28 straight-pull spokes to enhance durability. The 12-speed Shimano drivetrain supplies crisp shifting across the wide range 10-51t cassette, and the XT M8100 brakes provide superb modulation for a controlled ride.
