Wheels
When it comes to wheels, the 3900 Disc bike is equipped with the 26″ aluminum model. Being a little smaller, these wheels will fit both small and tall riders. However, you will need increased suspension than in the case of 29″ wheels.
Brakes
For your safety, it is important to have quality breaks on your bike. Trek 3900 Disc has Mechanical Disc brakes installed. These brakes are also very popular, and a lot cheaper than hydraulic disk brakes. However, performance-wise there is room for improvement.
