First up - what could cause "chain suck"? Could the cassette be too tght? I have just had a whhel built, everything seemed firn. Fitted the cassette and tightened it up. So far, so good. BTW, not so tight that I was straining etc. Fitted the whell, re-fit the chain, then everytime you spin the crank and then stop therear mech sort of fouls up and yhe chain is bashing the frame.
Secondly, having spent a while and a sum of money in obtaining a Curve crank, I find that the chainrings I have won't fit!! What will fit? It's a five arm job if that helps.
