Exactly as expected and at a low price

DI2 upgrade groupset

Order was delayed for a couple of weeks due to Blackfriday rush, but had good communications and set was delivered in excellent packaging, will order from Vanilla bikes again.

Excellent value if you’re not in a hurry.

On ordering I was informed delivery would take around 2 weeks - in the end it took around 4 weeks (I’d bought it as a present and it was getting very close to Christmas).
I rang Vanilla and they were very helpful - providing me with a delivery date which was then duly met. So as long as you don’t need the upgrade quickly I would definitely recommend using Vanilla.

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
