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.
30 Day Returns
We offer a 30 day returns policy. We will only refund return postage costs on damaged/faulty goods (a postage receipt will be needed). Refunds will only be returned to the original payment method – this may take up to 10 days to appear depending on how you paid.

Alloy 5 beam spider carrier with 3 alloy, 5 titanium and 4 Chromoly sprockets make this a lightweight, stiff and durable 12-speed Micro Spline MTB cassette
Hyperglide+ sprockets have a computer designed tooth configuration with contoured shift gates, resulting in 1/3 faster shift time than current HG cassettes providing seamless, smooth operation even under load
10-51T wide ratio gearing allows a more efficient use of energy through finer cadence control in ever changing trail conditions
Sprockets are cut away extensively and drilled to further reduce weight without reducing rigidity
Sprockets use hard anodising and nickel-plated finish for added durability and resistance to corrosion
For use only with Micro Spline freehub bodies
Alloy cassette lockring
For use with Shimano 12-speed SIL-TEC chains
Average weight 367g
