Mountain bike Orbea Onna 29 20 2026 tanzanite/silver

Frame
The Onna 29 20 uses a lightweight, hydroformed aluminium frame with internal cable routing, a tapered head tube and provision for a 27,2 mm dropper seatpost. This delivers stiff, precise handling, a quiet cockpit without rattling cables, and easy upgradeability for more advanced off-road riding. 

Suspension and control
A RockShox Judy Silver fork with 100 mm of travel is fitted at the front, providing effective absorption of small bumps and stability on rough trails. The fork’s settings allow quick adjustment to different surfaces, so the bike remains predictable in corners and under braking – from gravel roads to easier trails.

Drivetrain and brakes
The reliable Shimano CUES 1×11 1x drivetrain offers simple operation and a wide gear range for climbs, while reducing the chance of chain drops and cutting shifting time. Shimano hydraulic disc brakes deliver powerful, consistent braking in wet or dry conditions, enhancing safety on everyday rides.

Wheels, tyres and handling
The Onna platform is designed for 29-inch wheels and has plenty of clearance for wider MTB tyres, increasing grip and comfort. The Kenda Booster 2.4 tyres (29″) roll quickly on hard surfaces while still offering good grip on the trail – an excellent combination for recreational XC and everyday off-road rides.
