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.

Summary

The Trek Fuel series is celebrated for its innovative frame design and versatile performance, making it a standout in the mountain-youth category. Its suspension system, particularly the Active Braking Pivot (ABP) and RE:aktiv technology, delivers a plush ride that excels both uphill and downhill. The bikes are noted for their stiff frames, efficient climbing, and confident handling, though some models could benefit from upgrades like tubeless wheelsets and dropper posts.

Pros
  • Innovative frame and suspension design

  • Efficient climbing with good traction

  • Confident and balanced handling

  • High-quality components and durable construction

  • Versatile performance across various terrains

Cons
  • Non-tubeless wheelset and tyres on some models

  • Lack of a dropper post in entry-level builds

  • Narrow bars limiting aggressive riding

  • Basic wheelset with workaday hubs

  • Some models have front suspension that can't match the rear's performance

Key Quotes

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.
