This may be a dim q, but here goes…
If you have a (road) frame currently running Shimano ultegra rotors 140mm front and back (flat mount), and you wanted to put a SRAM groupset on it which came with 160mm rotors, what are your options?
Can you just use the existing Shimano 140mm rotors in the SRAM calipers (as a friend is adamant they will), or do I need to swap for 140mm SRAM rotors? I know that a 160mm will go in the fork (pretty sure I just flip the mounting bracket the other way up), but the frame manufacturer states “140mm is the maximum recommended diameter for the rear but a 160mm will go” - make of that what you will!
Best solution here folks?
