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?

Bible Review: Trek Top Fuel 9.9

Jan 2020

The new Top Fuel is still very much an XC machine. It's also damn fun and vastly more versatile than we expected.

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

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

Jun 2019 · Jessica Coulon

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.

2019 Trek Top Fuel 9.8 SL 1st Ride Impression

Feb 2019 · Dale Tiessen

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.
