The Trek 3900 Disc provides thrills from the top end of the market whilst minimising the chance of spills thanks to its mechanical disc braking system.
Although this might be described as a beginner’s bike or a casual cycle it is by no means lacking in character. The aluminium frame will not weigh you down and will be a solid supporter of all your efforts. Meanwhile the SR Suntour spring-loaded shock on the front fork will absorb the inevitable bumps that can rock and ruin lesser bikes. In addition, the Tektro disc brakes are a welcome sight, providing superior stopping power, which cannot be matched by calliper brakes.
The dark blue paint job of the Trek 3900 Disc looks great. Branding is present from the various contributing manufacturers and so those in the know will be able to appreciate its abilities, from the Bontrager tyres to the Shimano gears.
