The 2024 Trek Marlin 7 Gen 3 Hardtail Mountain Bike is your best friend on the trail and wherever else you roll thanks to its confidence-boosting trail geometry.

The Marlin 7 is built around a lightweight aluminium frame with modern trail riding geometry and internal routing that keeps cables protected and the bike looking sleek. To fit the widest range of riders the frame and wheels vary according to the size. The XXS size used 26" wheels, the XS and S sizes come with 27.5" wheels and the rest of the sizes use 29" wheels. In addition the XXS and XS bikes come with a curved top tube to further reduce the standover height.

The Marlin 7 has the perfect balance between price and performance with an upgraded RockShox suspension fork that makes quick work of rocks and bumps in your path and the huge gearing range of a SRAM 12-speed SX Eagle drivetrain.

This bike is perfect for

Mountain bikers who want a go-anywhere trail bike that's got upgrades where it matters most, but won't break the bank. You want to build skills on the trail, and need a bike with confidence-inspiring geometry and upgraded components that can keep up with your progress.

Key Features
  • The Marlin Gen 3 gives you serious trail capability with bigger tyre clearance, internal dropper post routing, ThruSkew rear axle and longer, slacker geometry that gives you more stability on steeper trails and at higher speeds
  • Its upgraded RockShox fork gives you 100 mm of suspension for turning rocks and roots in the trail into smooth-sailing
  • Rack and mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
  • Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending
  • Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount

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.
