IT STARTS HERE

A lifetime of mountain biking begins with a first – An initial curiosity, a spark of adventure, the inkling that there is much to discover under the branches of towering pines or among painted desert spires. After uncertain early pedal strokes comes an efficiency of motion and mind that changes the synapses of your brain forever. Strength arrives, discomfort departs, clarity comes even if only for the moment. A lifetime of mountain biking starts here.

ONNA MEANS COMFORT AND CONTROL

We designed the Onna for the rider who wants to conquer the trail. A bike geometry that maximizes efficiency and control is perfect for any rider who is learning to love MTB.

BALANCED HANDLING

Onna boasts balanced geometry with perfect trail manners to maximise the fun for all riders. Add wheel sizes matched to frame size give perfect fit for all riders and the Onna is ready for the trail ahead.

READY FOR THE TRAIL

With tapered headtube to give a wide choice of 100mm suspension forks, hydraulic disc brakes across all the range and 1x Shimano drivetrain on top models, Onna is equipped for the ride. With plenty of room for wide mountain bike tyres for comfort and grip, Onna isn´t going to limit your adventures.

ADVANCED ALUMINIUM FRAME

Onna´s advanced aluminium frame with shaped tubes allows us to fine tune the ride quality. Stiff enough to be fast and responsive, compliant enough to be comfortable and controlled. At Orbea we are proud that the Onna is ready for whatever trails lie ahead.

DROPPER POST READY

Onna is fully compatible with internally routed 27.2mm dropper posts, so you will be ready for whatever trails the future holds.

HYDRAULIC DISC BRAKES

Post mount 160mm hydraulic disc brakes on every Onna.

THREADED BOTTOM BRACKET

Threaded bottom brackets offer low maintenance are easily replaceable by the home mechanic.

TAPERED HEADTUBE

A tapered headtube and fork steerer put strength and rigidity where they’re needed while trimming weight with alloy steerer tubes and offering a wider selection of quality forks.

QUICK RELEASE AXLES

Onna comes with QR axles as standard.

INTERNAL CABLE ROUTING

Internal Cable Routing is carefully guided along the best path behind the headtube with no rub or rattle.
