This groupset shifts like a dream. Braking is excellent too. Super fast shipping from Merlin. Highly recommended.
Got fed up messing about with cables and decided to upgrade to di2. This was cheapest I could find and and as bike already had R8000 mechanical set up it was ideal for me. Would definitely recommend if you fancy changing to electronic gears. Easy to fit and great to use. You might need a couple of accessories such as cable tie set to prevent wires rattling inside frame and also di2 grommets for snug fit on wires.
This was my first Di2 kit. I am very happy with both the way it looks and operates. Gear changing is very smooth and reliable.
Excellent delivery. The DI2 just delivers smooth and perfect gearshift. BUY BUY BUY, worth every penny!
This product is superb, looks good and works perfect. and also very easy to adjust and make setups .
A lovely upgrade that makes all gear changes super smooth.
The Di2 kit is great, easy to fit on a bike with internal routing. I was very impressed by how smooth the shifting is. I`ll upgrade my other bike too. Very quick delivery, was delivered to Australia in 5 days.
I am very pleased and satisfied with the purchase. I put it on the bike and it was perfect. The after sales service is magnificent
The Di2 kit is the best upgrade, I came down from Dura Ace mechanical to Ultegra using this kit, and don't regret it at all. I am thinking of upgrading another one of my bikes.
The Ultegra DI2 is awesome, touch heavier than Dura Ace but same functionality. Awesome.
