After a recent failure of my Mderckx EMX1 the Merckx company have sent me a brand new Sallanches 64 frame. Whilst this is very nice of them it has caused some issues. Obviously time has moved on and Merckx now supply all their bikes with Shimano. So compatabiliy issues exist between my old groupset and the new frame. There are three main issues
1. Seat tube diameter - no big deal I need to buy a new seat tube.
2. My front mech is band on but the new frame has a hanger - can I modify the old mech or do I need to buy a new one?
3. bottom bracket - I'm really at a loss here. The new frame has a 50mm diameter shell which is also wider at approx 80mm than the old one. assuming I buy a new BB will I be able to use my old crank and do I need adapters etc?
sorry if these questions seem stupid but I've never done this sort of bike build before
