DESCRIPTION
The Trek Top Fuel 9.8 is a lightweight carbon trail bike built to rip up climbs and stay playful on the way down. A 120 mm rear and 130 mm front RockShox suspension package, with a Pike Select+ fork and Deluxe Ultimate shock, gives it the confidence to handle roots and rocks while keeping things fast and efficient. A wireless 12-speed Shimano XT Di2 drivetrain delivers ultra-smooth, precise shifts, and Smart Wheel Sizing fits 27.5" wheels to the smallest frame and 29" to the rest. It is a quick, capable down-country bike for riders who like to cover ground.
