Will do Shrader, Presta or less common Dunlop valves.
If your ridgeback is hybrid will probably have Shrader valve tyres or if a racer will have Presta type valves.
Shouldn't be a problem.
You need to look at the tyre guide pressure and valve type.
if guide pressure is over 160psi - this pump is no good.
I would think it highly unlikely that this won't be sutiable for your needs as you sound like an average non-technical user.
