I have been riding a Cannondale System Six but am now on a Colnago Master Olympic. They are both 56cm and I have measured everything so that the distances are the same, BB to saddle top, saddle nose to bars etc and all are the same, BUT, having ridden hard for the last two weeks I feel like I am only using the 4 inches directly above the knee (ie the base of the quads) to pedal with rather than the whole quadriceps group. Its not painful in the knee, but for the rest of the day after a hard session, stairs are like I hadn't ridden for months and hills are tough !

So what do I need to change, clearly the angles of the two bikes are completely different the 'Dale is much steeper, do I drop the post, raise it, move the saddle forward or back ???

Any help would be gratefully received as I am off for a fortnight in the Alps and Pyranees in a month and will not make it if I can't sort the problem out.

Cheers
Sean

    Is your saddle tip the same horizontal distance behind the BB centre on both bikes? Sounds like this might be the problem from your symptoms and you don't mention this measurement specifically. Also is saddle top to bar DROP identical?

    Different pedals/shoes (stack height), crank lengths, saddles (for the saddle tip to bars measurement) and handlebar reach (when riding on the hoods or in the drops) and choice of levers (Shimano/Campag/SRAM) may also be differences to consider.
