I'm planning on building up a road bike and have been offeyred some stuff for the build inc. modern Tiagra groupset and a pair of older wheels in great condition - Campagnolo Record hubs & cassette/Mavic CXP30 rims
Question 1. Are there any compatibility issues with Shimano mechs/shifters & Campagnolo cassettes.
Question 2. Can I fit 700x28c tyres on 622-13 rims. It's just outside Sheldon's recommended sizes, but I understand there is some room for manoeuvre with sizes.
