Trek Top Fuel 8 Gen 4 2025

Brands:
SKU: N/A

R65 000.00

The Top Fuel 8 Gen 4 is a nimble alloy trail bike that strikes a balance between quick climbing efficiency and descending confidence. It packs in a versatile 130 mm front and 120 mm rear travel for ripping over rocks and roots without sacrificing power on ascents. It’s built from lightweight Alpha Platinum Aluminium that helps save your budget for bike trips, but packs in upgrades where they matter, like a 12-speed Shimano XT and SLX drivetrain, and a Fox Rhythm 34 fork.
