Summary
The Trek Fuel series is celebrated for its innovative frame design and versatile performance, making it a standout in the mountain-youth category. Its suspension system, particularly the Active Braking Pivot (ABP) and RE:aktiv technology, delivers a plush ride that excels both uphill and downhill. The bikes are noted for their stiff frames, efficient climbing, and confident handling, though some models could benefit from upgrades like tubeless wheelsets and dropper posts.

Trek's Fuel EX 7 29er contains modern bike technology with a classic ride feel
No matter where and how we rode it during our year-long test the Fuel EX reaffirmed the outstanding credentials that earned it its 'best in test' badge
If your long-legged enduro bike is a chainsaw, the Fuel EX rides like a surgeon’s scalpel.
The carbon fronted Trek Fuel EX 9.7 29 is easily the stiffest bike in those we tested.

The Fuel EX and Tallboy are both brand new and impressively capable trail bikes, but which one do we prefer? Levy and Kazimer ride both and pick the winner.

Let’s be clear - Trek’s Top Fuel is a XC race weapon. This is not your typical ‘Whistler XC’ bike, which the greater industry may characterize as a ‘trail’ or ‘all mountain’ bike. The Top Fuel is designed for World Cup XC race courses. It is meant to be precise, light and fast.

You’re only looking at around 150g in weight saving over an aluminium frame, but the carbon fronted Trek Fuel EX 9.7 29 is easily the stiffest bike in those we tested.
