Excellent groupset for the serious amateur cyclist
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.

upgrade económico. vale a pena.
Fácil montagem e funcionamento perfeito.
Excelente relação preço/qualidade.
The 6800 group shifts and brakes perfectly at all times, and is not too expensive at that. The crankset with 110mm thru axle is easy to convert from compact into double and the other way around. The calipers have a double pivot so you can adjust your braking to the situation. The front derailleur has a longer stroke to ease shifting. The rear derailleur has a short cage and light tension so it immediately reacts to the shifters. The included Shimano brake and derailleur cables are treated with polymers. They have less friction during braking.
