The 2021 Trek Top Fuel 7 SX Full Suspension Mountain Bike is a mountain bike that fuses the flat-out speed of a cross country race bike with the trail-munching appetite of a trail bike. It lets you fly up climbs, hammer through flat sections and keep on truckin' on rough descents.

The Top Fuel is part of a new generation of shorter travel bikes that are perfect for lots of UK riding. It is based off race bike geometry but comes with 115mm of travel at the back and 120mm at the front. If you want to go marathon racing these bikes will do it but they also make for great all-round bikes. They are light and fast enough to make climbs a breeze but have enough travel and grip to let you take on the toughest trail centres.

This is a versatile bike and is packed with extra features including a Bontrager DropLock's shifter-style lever which lets you easily lock out both front and rear shocks at the same time for added sprinting or climbing efficiently. Plus, it controls your dropper post too. The Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride and you get a Straight Shot downtube for extra-stiff, responsive handling without added weight and a Knock Block headset that protects against spinning bars and fork crowns.

The Top Fuel 7 SX comes with SRAM SX Eagle 1 x 12 speed gearing and Shimano hydraulic disc brakes. Tubeless ready wheels and tyres and a Rockshox Judy Gold Solo Air fork make for a great value build.

This bike is perfect for

Mountain bikers who want a fast bike that climbs like a dream but still has enough travel and capability to handle rough trail centres and the toughest natural trails. With a great value build this is a bike that is ready to go but also easy to upgrade.

Key Features

  • 115mm travel at the back and 120mm at the front
  • Fast cross-country inspired geometry
  • 12 speed SRAM SX Eagle gearing
  • Tubeless ready wheels and tyres and dropper post

Mountain Bike Buying Guide

Mountain biking is an incredibly diverse sport. Mountain bikes now come in three main flavours. They are XC, Trail and Enduro.

XC – short for cross country, are quick race bikes. They will normally have 29” wheels and come with 100mm of suspension. If you are mainly going to be riding bridleways and natural trails in the South East of England, where our shops are, an XC bike will be the quickest and most efficient option.

Trail – these bikes are designed to be pedalled up and down hill and for use on bridleways and natural trails, but also at dedicated trail centres. They normally come with 130mm or 140mm of suspension travel and can have either 27.5” or 29” wheels, but 29” is quickly becoming the norm. Trail bikes are good all-rounders. They won’t be as fast as an XC bike on the flat but they can handle a lot more challenging terrain, and a few jumps. If you plan on taking your bike to trail centres in Wales, or to the Alps, then a trail bike may be your best option.

Enduro – enduro racing is a thing in and of itself but many people buy enduro bikes for ‘aggressive’ trail riding and uplift days at places like Bike Park Wales. This generally means challenging downhill trails with some big jumps. With around 160mm of suspension travel enduro bikes can take some big hits. They are designed to be efficient enough to pedal up hills but really come into their own when pointed downhill. You get enduro bikes in either 27.5” or 29” wheel sizes as well as mullet setups of 29 at the front and 27.5 at the back.

Men’s and women’s mountain bikes

Nearly all the mountain bikes we sell are now unisex. All of the big brands have gradually stopped doing dedicated men’s and women’s bikes over the last few years. Instead they are focussed on producing bikes in a bigger range of sizes. So, for instance, the Trek Marlin 5 is a unisex bike that now comes in sizes from XXS to XXL large. This means it will fit riders from 4’ 5” to 6’ 5” and everything in between.
