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!
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.

This downhill-specific cassette is built around an optimised 7-speed, 10–24T range, engineered to deliver small gear steps for maximum power and acceleration. Using a full X-Sync tooth profile, it provides the most consistent and robust DH shifting SRAM has produced, maintaining flawless performance even under heavy load. Designed so riders never need to ease off when dropping gears, it helps reach race splits faster and maintain momentum on the most aggressive courses. Two variants are available—XD and the new XD SLIM—allowing compatibility with standard hubs or improved spoke bracing angles on 148 mm DH rear ends.
