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.
We want you to be completely satisfied with your purchase. If something isn’t right, here’s how we can help:

Brand:Shimano Grx
Code:RDRX717SGSA
Shimano GRX sets itself apart with gravel-specific ergonomics, optimised gearing options, rugged reliability, and a quiet, stable drivetrain.
The Shimano GRX RX717 Di2 12-speed rear derailleur provides precise and clean wireless shifting. It features an integrated on-board removable battery (BT-DN320 sold separately) protected within the linkage and a crash recovery function that absorbs impacts and returns the derailleur to its original position. The Shadow ES system uses a dual-spring chain stabilising switch to reduce chain bounce in rough terrain, maintaining stable drive and shifting. This system is zero maintenance with no degradation of performance. The unique structure uses two springs for a tighter chain wrap, improving shifting and security with a 70% increase in spring force, allowing the chain to mesh firmly with the sprocket and preventing skipping as cogs wear.
