TRP HI/RD Hydraulic Disc Brakes installed!
First impression on TRP HI/RD: smoother and quieter than Avid BB7 road. These got installed on my 2014 Specialized Roubaix SL4 Disc. I got tired of the squeaking, whining, and grinding of Avid BB7 Roads. I tried new discs and new pads - and the problem never went away. After a big descent or a ride in wet conditions, the BB7 disc brakes would start obnoxiously screaming. Original setup: I had a similar problem with BB5s and then BB7s on my 2013 Specialized Tricross Steel Disc. The problem was even force due to flex of the steel frame. TriCross: More on these after riding a while.
