A bike with lower gearing will be easier to ride up steep hills, while a higher top end means it will pedal faster down hills.

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

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 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,

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

Trek Top Fuel 8 review

Jul 2018 · Guy Kesteven

Stiff frame and suspension in classic race style, but wheels are slow and ride feel is conservative. Buy if you want an efficient and trusted ride for your money

Highs
  • Stiff frame with suspension tuned for efficient pedalling, reasonable kit for the cash

Lows
  • Conservative rather than combative handling character and overall feel, wheels and tyres undermine rough rolling speed and liveliness

Trek Top Fuel 9 (2017) review - MBR

May 2017 · James Bracey

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.

Highs
  • Rewarding ride provided by the Re:aktiv suspension.

  • SRAM X1 groupset performed flawlessly.

Lows
  • Handling is marred by the miniscule bar width.

  • Tyres are inappropriate for most British conditions.
