The UK prices are very good. I had a near new 10 speed record set up on my bike but liked the shape of the new shifters. So instead of going with a new 11 speed set up I just swapped out the Record QS shifters for a new set of Centaur. The Centaurs are the new shape but they are 10 speed. Some purest may scauff at putting such a low end shifter on a Record set up but I don't care. They work great and feel even better. The Record/Centaur set up has a couple more seasons to go then maybe I'll go 11 speed, maybe not.
