Overview
It's right for you if...
You want an alloy full suspension that's ready to rip. You like to ride everything from cross-country hot laps to all-mountain adventures, and you need a bike that's light, versatile, and confident. You've got an appreciation for the durability of aluminum, but want upgrades where they matter, like your drivetrain and suspension.
The tech you get
An Alpha Platinum Aluminum frame equipped with a 4-way Mino Link lower shock mount for tweaking geometry and suspension leverage rate. A 130mm FOX Rhythm 34 fork with Float EVOL air spring and GRIP damper, plus 120mm of rear travel from a FOX Performance Float shock with a 3-position damper. It's topped off with a Shimano XT/SLX 12-speed groupset, hydraulic disc brakes, a Bontrager Line dropper post, and Tubeless Ready Bontrager Line Comp 30 wheels.
The final word
Top Fuel 8 Gen 4 is ready to cut loose from all-day climbs to rooty descents. It balances capability and efficiency, with just enough travel to keep the ride smooth without eating up your pedaling power. It gives you the perfect blend of affordability, with a rugged alloy frame, and upgrades where they matter, like the Shimano XT/SLX drivetrain.

Just took my Top Fuel 8 out for a spin in the Peak District and wow! Climbing feels so much easier and the descents are an absolute blast. So responsive and nimble. Honestly, the best mountain bike I've ever owned. Highly recommend for any woman looking to up their game on the trails.

I've been riding for years, and this bike is a game changer. The Top Fuel 8 is light, agile, and gives me so much confidence on technical trails. I was worried about the investment, but it's worth every penny. Makes tough climbs feel easier and the descents are seriously fun. Can't wait for my next adventure! It's beautifully crafted, and the attention to detail is superb. Trek has really nailed it with this model.
