Trek Top Fuel AL Gen 4 Frameset

The Top Fuel AL Gen 4 frameset is an alloy trail platform designed to make your dream bike a reality. It draws on Top Fuel's versatile geometry to provide the foundation for your dream bike: build it light and efficient with a 120 or 130mm fork, or choose a more aggressive all-mountain setup with 140mm travel.

• Alpha Platinum Aluminium frame, 120mm
• Claimed weight M - 3.70kg

Highlights

• Customise Top Fuel: Choose lightweight components and a 120mm fork for a featherweight Top Fuel, or opt for a 140mm fork and longer-travel 130mm rear suspension for extra versatility. Make the most of the clearance for a longer dropper seatpost and MX wheels, and customise Top Fuel to make it the ultimate trail bike.
• 4-way Mino Link: Easily adjust the suspension and geometry in four different ways to suit where and how you ride. With a simple flip, you can make the suspension more or less progressive and change the geometry to ride with a slacker head angle and lower bottom bracket or a steeper head angle and higher bottom bracket.
• New internal storage with new BITS bags: The new internal frame storage bag lets you leave your backpack at home while still carrying everything you need for your ride.
• Active Braking Pivot: Active Braking Pivot technology has allowed our engineers to optimise how the suspension responds independently to acceleration and braking forces. This means more confident control when you need it most.
