I grabbed a set of these and MTX gold pads to upgrade from the centerline rotors and sintered pads on my Ripmo with Code RSC brakes. Now I don’t have to pull so hard on the levers and don’t get arm fatigue. Beware when resetting your pistons when installing these, I had a hard time to get them to travel equally and center the caliper, but that’s not an issue with the pads or rotors. Had to find a good video how to service the pistons after a full bleed.
Nice upgrade from OEM.
I wanted to try the 180mm HS2 rotors for my 2022 stumpjumper to replace the SRAM centerline rotor. Nothing wrong with the centerline but the HS2 offers easier stopping power without squeezing your brake levers too tight. My brakes became more sensitive and responsive. The rotors are thicker so it was initially harder to install my rear wheel but I like them so much, I need to grab the 200mm for my front!
HS2 6-Bolt Disc Brake Rotor
They had what I wanted and I’m looking forward to mounting it to give it a go.
