I am seeking some know-how. I have a frame with Shimano callipers and a totally clapped out 700c centre lock hubbed wheel. I am looking at budget wheels. There are few ready built centre lock hubbed wheels at less than a weeks wages, but plenty of wheels with 6 hole hubs to take a basic rotor. My question is will these wheels with discs fitted simply drop into the existing calipers which at present have centre lock discs, or will they require adaptors or whatever. This is my latest project, N+2 
Thanks.

Thanks.
