FX 3 components
Fork material
The fork is made out of carbon, so, its weight is considerably lighter than one made out of steel. However, they cost a bit more than steel forks.
Wheels size
When leaving the production line, the FX 3 model has 700c aluminum wheels. There is no doubt, that 700c wheels are very popular on all road bike models. However, while they give you great speed and control, these wheels are not so bump-friendly.
Brakes
For your safety, it is important to have quality breaks on your bike. Trek FX 3 has Rim brakes installed. Rim brakes are cheaper than hydraulic brakes, and also easier to maintain. However, they are not nearly as effective as hydraulic brakes are.
