Tires
The double-walled aluminium rims are light and durable. For transporting the bike, we've made it easy to attach/detach the front and rear wheels. They are equipped with a quick-release system. The tyres use SkinWall technology. This process allows you to reduce their weight, therefore increasing performance, grip and comfort. 24-inch 1.7 to 2.2 cross-section inner tube with Schrader valve.Pressure indicated on the tyre sidewall (between 2 and 3.5 bar).
