Hi All,
Hoping for some help - building up a Blue Pig 2020 frame using old parts scavenged off other bikes. I have a pair of 203mm SRAM Guide R's.
I'm trying to work out what the frame post mounts are on the frame but there's nothing on the website to tell me that I can see other than it will take up to 180mm rotors. The full build bike comes with a 180mm rear brake, but the pictures make it look like there's an adaptor there.
As mentioned, I have a 203mm SRAM rear brake and cannot currently mount the caliper on the frame and accommodate the disc rotor. If I just buy a 180mm rotor will everything just work or will I still need an adaptor? I'm so confused by all the different mounts - I know the frame is post mount, but not sure what adaptor I'd need to run 180mm, if i have to buy a SRAM one, or can I get a Shimano/TRP etc one?
Thanks in advance if anyone can help
