Field Test Review: 2022 Trek Top Fuel - Same Name, Different Bike

Dec 2021 · Henry Quinney

For a bike that is so capable on the descents, though, the Top Fuel still packs a mighty punch when it comes to gaining elevation..

Highs
  • Great suspension performance

  • Frame storage

  • Strong climbing performance

Lows
  • Knockblock isn't as well executed as other brand's versions

  • Works well when pushing hard, but might not be the most comfortable for all

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

Trek Top Fuel 9.9 in review

Oct 2019 · Trev Worsey

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

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

Lows
  • TwistLoc system quickly gummed up and functioned inconsistently.
