Reviews over the

Shimano Ultegra 6800 11 Speed

The gear shifts are light, positive and quick and the braking is awesome when compared to my old Shimano Tiagra groupset - it really is a big step up in terms of performance. There are also significant weight savings to be made upgrading to the Ultegra groupset. Also great customer service from Mantel with easy online ordering and quick delivery! Would highly recommend.

Pros & Cons

I bought this group at a very good deal and I am very satisfied with everything only the cassette was not the size of my option one. The finish is excellent and it functions really good. As a first timer in bike building it was easy to mount.

Great quality upgrade for my bike.

New ultegra groupset looks and works really well for the price. Excellent price and service from mantel. Only thing I could score it down for is not having cassette/ front mech/ bb choice but really can't complain at this price
