Pre-Order

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

Your 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; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

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 & Collection 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 & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Trek Marlin 5 Hardtail Mountain Bike 2023 in Azure Blue

Season:2023

Brand:Trek

Code:345872022Azure

The Trek Marlin 5 is a trail-worthy daily rider that's perfectly suited for everyday adventures, on and off the trail. An upgraded suspension fork (compared to the Trek Marlin 4), 16 speeds and mounts for a rack and kickstand make it an ideal choice for new trail riders or anyone looking for a comfortable, stable commuter with the ruggedness of a real mountain bike.
The Marlin 5 features a lightweight aluminium frame with internal shift cable and brake hose routing to protect your cables and add to the bike's sleek look and a suspension fork that takes the edge off bumps and rough terrain. The smaller frame sizes (XXS, XS and S) have short-reach brake levers that make it easier and more comfortable for riders with smaller hands to brake confidently and a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount, so you get a bike perfectly moulded to your size.

This versatile hardtail delivers a great ride for all your adventures, but also doubles perfectly as a commuter bike so you can get the best of both worlds!

Key Features & Benefits:

  • SR Suntour suspension fork: Upgraded over the Marlin 4.
  • Hydraulic disc brakes: For reliable stopping in all conditions.
  • Shimano 16 speed gears: To get you up the steepest of hills.
