really simple – NEW CODES (r,rsc) use 2011+ code brake pads, which are also the same as GUIDE RE. (as they share the same caliper)
fwiw – im trying everything quieten down my code rsc – sintered sram pads are the noisiest pads ever used when even a hint of moisture in the air (just damp)
tried a set of genuine organic replacement pads and much better bite and way way way quieter, still make a noise in the wet, but its only for a few secs max then it clears, and they feel loads better
just one the hunt for another set cheap, though ive also got some nukeproof semi-metallic to try too hopefully a bit longer than organic out back but not as loud as sram sintered
I liked the uber racematrix in summer, but they are just as loud in the wet as the sintered sram ones, and they have no bite in the super wet ive found
