Needed Items for Rotor Upgrade
My 2019 Santa Cruz Bronson V3 is the bomb! For my style of riding, it fits all my needs. In comparison to SRAM's Guide RSC brakes, the Codes are definitely better with lots of pucker power. Wanting more braking power, I decided to upgrade my rear rotor from to 200mm.
It was obvious I needed 20mm to accommodate the larger rotor. To my disbelief, SRAM didn't include any instructions with the kit. Rather than seeing spacers of equaling 20 mm, the kit came with two separately sealed packets of spacers and washers. In each separate packet was a common 12.5mm spacer. But the separate packets also included a 7.5mm and 17.5mm spacer. Ok, I get it; not all bikes are manufactured the same. I emailed SRAM whether my assumptions about its fit were correct (Using spacers that align the caliper/brake pads to the larger rotor) To this day, SRAM still hasn't responded. (I also wrote to Santa Cruz and they didn't answer either).
At any rate I chatted with a CC rep and he provided clarity on its mounting use. After mix and matching the spacers, I was able to align the brake pads to the rotor. Although 20mm doesn't seem like much, the difference in stopping power was instantly recognizable. Now I'm able to hit those steep and gnarly trails with a lot more confidence. Amazing!
From CC's standpoint, they get 5 stars from me! However from SRAM's viewpoint, they get 4 stars due to their lack of instructions and responding to customer inquiries. If you're thinking of upgrading your SRAM/Avid rotors, this is the kit to buy. But beware: It doesn't come with mounting instructions. So you'll need to mix and match the spacers to determine which best aligns to the rotor.
