High-end full-suspension mountain bike, designed for XC and trail routes.

Upgrades:
Mavic Crossmax wheels: they are better and lighter than the stock wheels on many builds. They increase stiffness and improve handling.
Scott handlebar: high-end aluminum, possibly wider than the original, providing more control.
Syncros stem: not the original Trek/Bontrager and usually a quality upgrade.
Shimano SPD clipless pedals: a good addition for XC and trail riding.
