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!


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 X-Caliber 7 Hardtail Mountain Bike 2021 in Mulsanne Blue




The Trek X-Caliber 7 is the perfect entry point to fast cross-country riding and racing. It's a fully capable hardtail mountain bike with expert tech where it matters most, like in the lightweight and durable alloy frame, RockShox fork, Shimano drivetrain and hydraulic disc brakes. This is the perfect if you're new to mountain biking and want a high-value bike that's perfect for local XC trails and even racing.

This bike has the same features found on higher-end bikes all on a platform that's easy to upgrade down the line. The X-Caliber 7 comes fitted with tubeless-ready wheels with wider Boost141 hubs for increased wheel strength and better tyre clearance, and the sleek internal cable routing gives you clean looks, protects your cables and makes it easy to upgrade to a dropper post for even more capability. The RockShox air fork has 100mm travel, rebound adjust and can be tuned to the rider’s weight, and it’s much higher quality than what you’d normally get on an MTB at this price. Overall, the Trek X-Caliber 7 is a great cross-country mountain bike at great value, that you won’t immediately outgrow as your skills advance.
