Dennis B.wrote a review of SRAM G2 RSC Disc Brake on May 20, 2020
Familiarity: I've put it through the wringer
Upgraded from a dual piston to this four piston on a 2019 Tallboy and now it's near perfect for my riding style. I am 6'4" 200 lbs and just needed a little more braking power and found it.
Installation was very simple and didn't require bleeding. I put about 20 rides on the brakes before bleeding and only got a couple small bubbles, no more than I get every 6 months or so with normal use with any brake.
I did have to bend out the brake pad springs, as they were making a funny noise but after that no issues. Love the new brakes.
