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.
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.
Can it get any better than this?

The Trek Fuel EX 9.9 is a classic in the trail bike segment.

The updated Trek Fuel EX now features storage in the downtube, 29er wheels, more travel and a gorgeous frame… oh and it’s rollicking fast too.
This is not what it looks like. Even though this new Fuel EX has a Fox 36, it doesn’t mean it has shed its trail-bike past for an enduro-bike future. Even
