If it's a no-cost option, 7900. I think the rolling element thrust bearings are the reason why all tests of alternative brakes can be summarised as "they're OK, but they're not DuraAce"
Thanks, just picked up a set for a tenner (couldn't turn it down), thought I could replace my BR-5700 with them which are currently on my winter bike. However seems like might go on my summer bike instead.
