For This Bike
Jan 2020 · Ed Thomsett
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

This year, the Trek Top Fuel has had a ground-up makeover, adding more travel, slacker geometry, more clearance, and most importantly a change in attitude.
Nimble and involving handling
Happy to step-up to tough terrain
Lockout is niche and adds complexity
SRAM Level brakes prioritise weight over power

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.

Trek's new Top Fuel XC race bike comes stock with 2.4-inch tires and a dropper post. A proper dropper. And while these are just a couple of the parts choices made by Trek's mountain bike development team, they're strong indicators of what this new bike is all about: more.

This is a XC race bike, and I should ride it as such without a dropper.

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.
