The 2021 "Top Fuel 8 NX" model from Trek is a versatile mountain bike designed for challenging trails and sporty rides. Priced at 3,099 EUR, it offers high-quality components and robust technical features.
The Top Fuel 8 NX’s frame is made from Alpha Platinum Aluminium and features a tapered head tube as well as Knock Block technology, which prevents the handlebars from twisting. The internal Control Freak cable routing ensures a clean look and protects the cables. Other features of the frame include a down tube guard, a magnesium lever and Mino Link technology, which allows the geometry to be adjusted. The Active Braking Pivot (ABP) and the Boost148 standard contribute to stiffness and stability. The frame offers 115 mm of suspension travel.
The bike’s maximum permissible weight is 136 kg, whilst the bike itself weighs 13 kg. This makes it a robust yet lightweight choice for demanding riders.
Braking performance is provided by SRAM Level T hydraulic disc brakes, fitted to both the front and rear. The front and rear brakes are fitted with SRAM Centerline discs, each featuring a rounded edge and a 6-hole disc mount. The disc size is 160 mm at the front and 160 mm at the rear.
The gear system is controlled by the SRAM NX Eagle 12-speed shifter, which enables precise and reliable gear changes. The RockShox Recon Gold RL fork, with Solo Air suspension and Motion Control damping, offers 120 mm of travel and ensures a comfortable ride over uneven terrain.
The crankset consists of the SRAM NX Eagle DUB with a 32-tooth steel chainring and a crank arm length of 175 mm. The cassette is an SRAM PG-1230 Eagle with an 11–50 gear ratio, offering a wide range of gears.
The handlebars are Bontrager Rhythm Comp aluminium bars, 750 mm wide with a 15 mm rise. The grips are Bontrager XR Trail Comp with nylon clamps, which ensure a secure grip. The stem is also a Bontrager Rhythm Comp, measuring 70 mm in length and featuring Knock Block technology.
The wheelset consists of Bontrager Kovee hollow-wall rims, which are tubeless-ready and have an internal width of 23 mm. The hubs are made of aluminium with sealed bearings and feature a 6-bolt disc mount. The front hub has a Boost 110 standard axle with a 15 mm thru-axle.
The saddle is a Bontrager Arvada with steel rails and a width of 138 mm. The seatpost is a Bontrager Line Dropper with a 150 mm travel and internal cable routing. The seat clamp is a bolt-on clamp with a diameter of 36.4 mm.
The bike’s packaging dimensions are 26 mm wide, 81 mm high and 163 mm long. The reach is 52 mm, the stack 62 mm, the seat tube length 56 mm and the top tube length 68 mm. The head tube angle is 68 degrees, as is the seat tube angle. The head tube length is 12 mm, the chainstay length is 43 mm and the standover height is 78 mm. The wheelbase is 123 mm.
The Trek Top Fuel 8 NX XXL BK is therefore a well-equipped mountain bike that impresses with its technical features and robust construction.
