The Top Fuel C Frame Set Gen 4 is a carbon trail frame with 120 mm of rear travel that's ready for your dream build. It takes the do-anything geometry of Top Fuel and leaves the rest to your imagination – build it up as a lightweight ride for soaring up climbs with a 120 or 130 mm fork or go all-mountain with a 140 mm fork. Go 29er or MX it up. The world is your oyster. Its four-position Mino Link means you can tune it to how you ride and however you want to build it.
