Pre-Order

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.

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 estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Shimano RD-R8150 Ultegra Di2 12 Speed E-tube Rear Derailleur

Brand:Shimano

Code:RDR8150

Ultegra shadow design with Di2 technology, shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear.

Features:
  • The rear derailleur is now the brains of the system with wireless connectivity to the shifters. It acts as the point the system is charged, provides Ant+ connection to 3rd party devises and replaces the handlebar junction
  • Button on the derailleur for Di2 operations, and led light denotes synchronized shift mode, setting mode and charge requirements
  • Sleek appearance with low profile shadow design construction reduces risk of damage in a crash
  • Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
  • The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts
  • Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
  • High tolerance cold forged aluminium link plates and body construction is extremely light and durable
  • Four self-lubricating micro-machined fluorine-coated link pivot bushings provide low-friction shifting
  • 12-speed e-tube Di2 compatible
  • Wide gear ratio compatible up to 11-34t
