Ultegra Di2 upgrade kit

You don’t seem to be able to get this kit at many places.
Purchased from Vanilla the kit took a little over a week to come due to stock issues but when it did it was great .
All the hardware & wiring to fit out an existing groupset.
All the wires in the kit are supplied it really is the real deal.
First class

Ultegra Di2 upgrade

Fantastic price on Ultegra shift kit - but be prepared to wait for your order!!!! 2 weeks from placing an order. Communication pretty poor, could be way better - I had to get in touch with them to ask when delivery would be, not impressed. I ordered something from Sigma Sports at the same time which took two days to deliver

Top service

Ordered the Di2 upgrade kit after speaking to them to confirm what was in the kit. Then realised I’d made the error in ordering the wrong rear mech. Emailed & called them the following day. No problem in changing the order. Order arrived within the timescale that I was advised. Kit fitted to bike & works perfectly. Top shop to order from.

Great product at the best price I could find

Really helpful company, good communication and really outstanding customer service. Bound to be using them again.

Great product

Easy mount, smooth shift, beautiful design.... What’s NOT to Like
