is this right no matter how many bikes you have the seat must always be the same distance from top of seat to floor

    no as the bottom bracket height differs from bike to bike, this said my 3 bikes are more or less the same.

    seat height is measured in relation to the pedals, but frame geometry and use will cause you to fine tune each one differently

    Agree with previous posts really, if pedalling efficiency is the most important thing for all your bikes that is. Atm I have a good old GT MTB with a tag-along attached to it most of the time. I'd say the seat is around 50mm lower than optimum just to give me a bit more of an opportunity to stick a foot out when we get the wobbles off-road... and that's using bear trap pedals as well!

    Assuming same length cranks and same pedals and shoes then yes. You should also be sat the same distance behind the BB. These two settings are the first and most important to get right.

    I had to rebuild my Cannondale in a hurry at the weekend after my Basso's bottom bracket packed up and I didn't have time to replace it before yesterday's Brian Robinson Challenge.

    I didn't have time to do a test ride, so I just copied the setup off the Basso, as best I could. The handlebars on both bikes were as high as I could get them, with stems flipped over - I suffer from back ache and don't like too big a drop to the bars from the saddle.

    The two things I could then change (without buying any new parts) were saddle height and saddle setback, settings which interact with each other. As you raise the saddle, it goes back more so it can take a few attempts to get both right.

    I made sure that the height and setback matched and then went out and did a tough ride. I was pretty happy with the setup. Even though the frame angles are not identical and the bars were a tad low on the Cannondale, the position on the bike felt close enough to what I'm used to on the Basso, as not to bother me.
