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.

Trek Procaliber 8 XC Mountain Bike in Desert Sage

Season:2027

Brand:Trek

Code:80405GRN

Procaliber 8 is a fast, capable cross-country hardtail built to chase singletrack PRs and line up for race day.

Its Alpha Platinum Aluminium frame delivers confident handling through tight corners and rough sections, while a 120mm RockShox Recon Gold fork smooths out the trail ahead. A wide-range SRAM Eagle 12-speed drivetrain, lightweight Bontrager Kovee wheels, and Shimano hydraulic disc brakes round out a build that is ready to push the pace.

Trek began removing high-emission aluminium from manufacturing in 2024, replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike Trek makes, including this one, has made the switch, driving a major drop in the footprint. Shimano XT is the original mountain bike groupset and is trusted by generations of mountain bikers around the world, offering reliable shifting, superior braking, and intuitive maintenance.

  • Alpha Platinum Aluminium frame
  • 120mm RockShox Recon Gold fork
