Trek Fuel EX 9.9 XTR Project One in bikepacking review

Oct 2020 · Benjamin Topf

The Trek Fuel EX 9.9 is an absolute classic in the trail bike segment. Could it also be the perfect bike for the next bikepacking adventure with its modern geometry and spare parts compartment in the down tube? We put the Fuel EX to the test.

Highs
  • Maximum fun on the descents

  • Intuitive and good-natured handling

  • Storage compartment in the down tube for tools or snacks

Lows
  • Too sluggish on easy terrain

  • Too much bike for long straights

  • Chain slap

Bike Review | 2020 Trek Fuel EX 9.9

Jun 2020 · Spencer Johnson

As warmer temperatures hit the Pacific Northwest and the dirt starts to dry, I’m always eager to get out on some long rides with some big climbs. Naturally, when this Trek Fuel EX 9.9 showed up at the Freehub office, I knew it was time to put the nimble beast through its paces. I challenged myself to a 60-mile sufferfest on some of Bellingham, Washington’s toughest climbs and descents. It definitely didn’t let me down. Climbing on this bike was a joy. Trek equipped the 9.9 model with its proprietary RE:aktiv shock with a three-position damper, which I left wide open for the entire ride. The rear suspension had an overwhelmingly supportive feel while pedaling out of the saddle, yet as soon as I hit a bump it dived deeper into the travel, keeping the rear wheel firmly planted and providing excellent traction. The geometry is modern and balanced, with a long reach and a sensible 76-degree seat angle. On the descents, the bike inspired confidence, thanks to its long wheelbase and bottomless-feeling suspension. My confidence was further enhanced by the reliable stopping power of the Shimano XT brakes. As a 200-pound rider, I couldn’t have appreciated the ultra-powerful XT brakes and the 203-millimeter front rotor more—especially while bombing down some of Bellingham’s scariest double-black trails.
