Orbea Onna 29 40 mountain bike black M20819N9 (M20819N9)

Orbea Onna 40, a mountain bike created with precisely designed geometry, is dedicated to MTB enthusiasts eager to explore new trails and improve their off-road skills. This machine is designed to provide optimal performance and vehicle control, which is invaluable for both beginners and more experienced lovers of riding off the beaten path.

The advanced suspension system in the fork guarantees a smooth and comfortable ride, regardless of the terrain. The ability to lock the suspension is key to quickly adapting the bike to changing trail conditions, allowing easy transition from soft ground to hard paths.

Hydraulic disc brakes with a diameter of 160 mm, mounted on every Onna model, enable precise braking, which is crucial for safety and control when riding in challenging terrain. The bike is also equipped with a reliable Shimano 2x9 gear system, providing a wide range of gears that allow smooth shifting in any conditions.

The head tube design, which tapers downward, and the fork steerer tube, made from alloy, provide the necessary strength and stiffness while reducing weight. This solution allows the use of various high-quality forks, increasing the bike's functionality.

Orbea Onna stands out with harmonious geometry and riding dynamics, translating into extraordinary sensations and enjoyment on every trip. Thanks to the intelligent selection of wheel sizes according to frame size, every rider, regardless of height, will find a model perfectly suited to their needs. Onna is therefore ready for any trail, offering unparalleled riding experiences.

In summary, Orbea Onna 40 is a bike that offers not only excellent riding characteristics but is also a synonym for technological innovation. Thanks to its versatility, it will be a reliable companion both during climbs to mountain peaks and exciting downhill rides. It is the perfect choice for anyone seeking unforgettable adventures on two wheels.

Advantages

Front cushioning
The cushioning on the bike provides comfort when negotiating bumps in the road. This model features front wheel cushioning, which absorbs the force when hitting an obstacle and increases the level of safety.
Aluminium frame
The aluminium frame is characterised by its high resistance to scratches and damage. In addition, this material is characterised by its low weight, which makes carrying the bike no problem.
Hydraulic disc brakes
This mountain bike is equipped with hydraulic disc brakes, which have a very low failure rate so that use will be trouble-free, even during frequent use. In addition, they feature greater braking power and modulation.
29" wheels
The use of 29 wheels has made it possible to provide more and better tyre contact with the ground, which makes it much easier to overcome bumps when riding over rough terrain. This size guarantees good stability when riding at higher speeds.
