2020 Trek Marlin 6 Mens Hardtail Mountain Bike Grey

Season :

Brand : Trek

Code : 287872020

Weight : 0KG

The 2020 Trek Marlin 6 in Grey is prefect if you're testing the waters of off-road riding and want a real mountain bike at great value price. It comes with a wide range of gears to cover more ground on the road and trail and a suspension fork with a lockout for better efficiency on climbs.

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 6 is the middle bike in the range. It has an efficient 2x8 drivetrain, hydraulic disc brakes that feel smoother than mechanical disc brakes and a suspension fork with 100 mm of travel.


This bike is perfect for

Riders who want a properly off-road capable bike on a budget. The Marlin 6 has the essential features you need for off-road riding and some nice extras like a lockout fork.

  • Rack and kickstand mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter
  • Like every Trek, it's backed by a lifetime warranty

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.

Estimated Delivery Dates

Estimated Delivery Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery Dates provided on product pages.
