My history of mountain biking started with a little wooden trike, with no pedals and wheels bigger than my head. I moved forward as any child does onto a bigger bike with bigger wheels and pedals. My parents always encouraged me to get outside and ride a bike, although I didn’t like the idea of mountain biking. I knew how to ride a bike; why go any further?

A front-heavy ride position and not-so-grippy tyres are the only limiters on this all-round speed demon
Makes the climbs fun and rips on the way down
An elegant package with a choice of colours
The six frame sizes span a massive range
A higher front end would give more descending confidence
Thin tyres don’t offer much grip or protection
Carbon wheels and bar bump up the price without a big impact on performance

The Top Fuel is Trek’s endurance cross-country race machine built to conquer climbs and inspire confidence on descents.

The new Trek Top Fuel Pulls the XC-race stick out of its butt and joins the trail bike party.
It's super light and fast as hell.
It's versatile—adjust the Mino Link and stem angle to fit your riding style.
TwistLoc system quickly gummed up and functioned inconsistently.

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.

Swing a leg over the Trek Top Fuel 9 and the first thing you notice is the suspension is keen to get working. It’s a seriously rapid bike on the trails.
Rewarding ride provided by the Re:aktiv suspension.
SRAM X1 groupset performed flawlessly.
Handling is marred by the miniscule bar width.
Tyres are inappropriate for most British conditions.

The carbon fiber Top Fuel ruled in mountain biking’s mid-2000s heyday, and now it’s back and better than ever. Most importantly, Trek has updated the
