First Impressions: Trek Top Fuel 9.8 GX

Oct 2020

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?

Trek Top Fuel 9.8 review

Jan 2020 · Ed Thomsett

A front-heavy ride position and not-so-grippy tyres are the only limiters on this all-round speed demon

Highs
  • 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

Lows
  • 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.

Highs
  • Nimble and involving handling

  • Happy to step-up to tough terrain

Lows
  • Lockout is niche and adds complexity

  • SRAM Level brakes prioritise weight over power

The Trek Top Fuel Finds Trail Religion and Is Reborn as a Fun Trail Bike

Jun 2019

The new Trek Top Fuel Pulls the XC-race stick out of its butt and joins the trail bike party.

Highs
  • It's super light and fast as hell.

  • It's versatile—adjust the Mino Link and stem angle to fit your riding style.

Lows
  • TwistLoc system quickly gummed up and functioned inconsistently.

First Impressions: 2020 Trek Top Fuel 9.9 XX1 | $9,000

May 2019

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.

[First Ride] The New Trek Top Fuel

May 2019 · Stefano Udeschini

A few days before the Riva del Garda Bike Festival we were invited to the official presentation of the new Top Fuel, Trek’s full-suspension XC / Trail weapon. You read that right, I also entered the word “Trail”, as this is how the bike was presented. Compared to the previous version it is defined as a more versatile bike, made with more balanced geometry and a lower weight. Let’s start with geometry. In the following images you can easily pick up on what the actual changes made to the frame were. It is easy to understand how they wanted to change the soul of the bike,
