Bad Nick The braking power from the RX4’s 4 pots is undeniably substantially greater than with a standard 2 pot calliper. The Hope brake hose fittings supplied, simply from an engineering point of view, are superior to those produced by some other well known rival brands. I have also used Hope ASS braided hoses including the brake lever insert adapters , allowing the use of Hope brake line fittings all round.. All excellent quality components that allow me the confidence to really hang off my brakes when I need to.
Andy Nice looking caliper, easy to fit, but not that impressed with performance, seems less powerful than the RS785 it replaced, organic pads are quite noisy compared to Shimano organics too.
