With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!


With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

2020 Trek Marlin 7 Hardtail Mens Mountain Bike Viper Red

Season : 2020

Brand : Trek

Code : 287892020VIPRED

The 2020 Trek Marlin 7 in Viper Red is where race-worthy mountain bikes begin. The Marlin 7 takes the great value Marlin frame and adds a smooth, lightweight RockShox fork and upgraded parts to make a great cross country hardtail that will hold its own against higher-end race bikes.

All of the Trek Marlin bikes are built around a lightweight Alpha Silver Aluminium frame with internal routing to protect your cables and add to the bike's sleek look. The frame is setup for off-road riding but also comes with all the mounts you need for pannier racks and kickstands so it can double-up as a tough commuter.

The Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you’re on the fastest wheel that fits. The smallest sizes come with 27.5” rather than 29” wheels and even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

The Marlin 7 is the flagship model of the Marlin line-up and has a high-quality RockShox fork with a lockout and 100 mm of travel, a 2x9 drivetrain, Shimano hydraulic disc brakes and a low-profile Shimano Shadow rear derailleur that's designed to avoid snagging on trail debris.


This bike is perfect for

Riders who are new to mountain biking and want a serious single-track ready bike with race-ready parts for superior performance so you can take on off-road marathon rides and XC races as well as bossing your commute.


Key features

  • All the value, plus all the versatility – it's a totally race-worthy mountain bike, with rear rack mounts if you use it for commuting too
  • It's really fun to ride, and feels like a much more expensive mountain bike
  • Great suspension at an even better price
  • The 2x drivetrain gives you all the gears you need and none you don’t
  • Like every Trek, it's backed by a lifetime warranty
