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.
