My Review of the Trek Top Fuel 9.8: One Bike, Every Trail
We all have those friends who have gear for every occasion, and mountain biking is no different. I have a couple of friends with garages that look like mini-bike shops. A beefy enduro bike, still covered in mud from the last enduro ride hanging from the wall, an old-school hardtail for spinning through rootless hand built single track and a freshly polished XC rocket for chasing Strava segments ready to go next to the door.
I’ve never had that luxury. My bank account has always kept that dream in check, so finding that perfect do-it-all bike has always been my goal.
I’ll admit that I’ve worked my way through more than a few bikes over the years, trying to find just the right one. My search for an all-in-one bike was seeming fruitless, until I came across the Trek Top Fuel 9.8. Marketed as a versatile trail bike capable of doing it all. While the marketing caught my attention, I wasn’t buying their claim. Always skeptical, I decided the only way to find out was to put it to the test.
I headed to the ruggedly diverse trail network at Sault Ste. Marie’s Hiawatha Highlands. With flowing berms, rooty singletrack, punchy climbs and steep, exposed slabs of the Canadian Shield, it’s arguably the perfect proving ground of a bike that claims to do-it-all.
Over the course of three days in late fall, I took the bike through its paces. With a mix of beautifully crisp dry fall weather, followed by a few rainy days that covered the trails with a carpet of slick, fire-toned leaves hiding every rock and root, I was able to test the bike in all conditions.
The first test was on the Farmer Lake Trail. An epic backcountry trail system known for lung busting climbs, beautiful views of Farmer and Crystal Lake and white-knuckle descents with steep granite slabs scattered throughout.
On the ups, the bike felt snappy and eager to climb. Trek’s lightweight OLVC carbon frame and responsive suspension made long slogs feel smoother and punchy ascents less punishing. Even on sustained climbs, I found that I could settle into a rhythm and spin comfortably without feeling like I was punishing my 47-year-old dad bod for trying to claim local legend status by winning a king of the mountain segment on Strava.
After the grueling climb, I decided to take a quick rest at the lookout over Crystal Lake—one of the thousands of beautiful lakes that dot the Northern Ontario horizon. Punctuated by a beautiful vista of the lake, complete with a small island and surrounded by endless mixed forest made crimson by the fall. It was a great place to rest my legs before I dropped into the fast-flowing descent, peppered with steep slabs of granite that define the Canadian Shield.
Going downhill, the Top Fuel quickly shed its XC roots and morphed into a plush trail bike. Steep, rowdy descents, no problem. The bike felt sturdy, plowing through rock gardens that would have most lightweight bikes twitching like an overcaffeinated office worker. Dropping into steep slabs is where I really noticed that the geometry hits that sweet spot. Thanks to its relaxed 66 degree head angle, the Top Fuel is slack enough to feel confident on steep, sketchy descents. Thanks to the short rear end, the bike was still agile enough to thread through tight switchbacks, and the responsive Rockshox Deluxe Ultimate RCT rear suspension kept the back wheel planted without any chatter.
After a couple of days on the bike, what surprised me most was how playful it felt. Flow trails with rollers, tabletops and berms are where this bike truly comes alive. It’s got that perfect mix of pop and stability, you can load it up through corners, boost off trail features and land smoothly without a hint of wobble.
Rolling back to the trailhead after my third day of riding, I was no longer a skeptic. My thoughts had shifted from whether I found the elusive do-it-all bike, to what I was going to do with all the extra space in my garage.
So, who’s this bike for? Riders like me, those who love big days on the trail but can’t justify or afford to own multiple bikes. Whether its flow trails, backcountry grinds or a quick spin after work, this bike covers it all.
If you’re looking for a bike that you can count on no matter what the trail throws at you, the Top Fuel 9.8 is the bike that won’t leave you second-guessing at the trailhead.
