Hi guys, I've decided to move to 203mm rotors front and rear, but am a bit lost on what IS adapters to use where. I've got IS mounts on the fork and frame; so, my question is: Can I buy two of these adapters from Wiggle: http://www.wiggle.com/shimano-disc-brake-caliper-adapter/ and choose the "Rear IS 203mm" option? IS is IS right? Or do I need a specific Front IS adapter? I've heard that the IS mount's spacing is different from the frame and fork, so could I theoretically just buy two different sized "Rear IS Adapters"? Thanks in advance!
