    If I stretch my hammies a lot, can I raise my seat?

    ........hammies, glutes, calves and back.

    Or, does raising the seat to a certain height inhibit the function of the hammies a calves when pulling up, regardless of muscle fexibility?

    And, what percentage of our power do we get from the up-stroke anyway?

    unless you can stretch the bones in your legs you may have problems... ;-)

    the upstroke? do you mean from bottom dead centre to top dead centre?

    I'm not very good at pedaling in circles, if that's what you're getting at.

    What I probably mean is the very start of pulling up/back, when, if you're too high or feel too tight in the hammies, you feel like you can't get much torque.

    I'm frustrated, because I feel that my seat is a tiny bit low for pushing down, but a tiny bit high for pulling up/back. So, i thought if I wasn't so slack with my stretching, it would all be sorted out.

    to set your seat height in the ball-park approximate area, stand in bare feet with your feet about 10 cm apart and measure the distance from the floor to your greater trochanter, click these links for image of your GT and where to locate it

    http://www.hkin.educ.ubc.ca/361/pages/greattro.htm

    Record the measurement. you'll need an assistant to measure.

    Then set the cranks to be directly in line with the seat tube. On the lower pedal, make it horizontal and measure from the surface where your foot rests on it, to the top of the saddle at the point where you sit on it. This measurement should be ~ 100% of your greater trochanter height.

    Not everyone will have it set at exactly 100%, you may need to move it up or down a couple of % from this initial measure, however, that should give you a good starting point.

    generally, people don't pull up on the that part of the pedalling cycle, unless e.g., you're out of the saddle sprinting. during normal cycling (including racing), the majority of the force you apply to pedals is during top dead centre to bottom dead centre.
