Am I correct in thinking that one cannot practically use all the gear ratio combinations because of the angle of the chain across the cogs? So even if one has 7 or 8 on the rear cassette one doesn't use the two larger rings in conjunction with the smallest of the front set and same applies the other way around. so practically mountain bikes have say 13 or 16 useable combinations.
