    Is my bike the right size?

    I got a Gravity Liberty CX bike at 54 cm. I am 5"10.5' tall. The seat, at it's lowest point, has me on tip toes to touch teh ground. Only when getting off the seat can I touch the ground with around 1.5 of clearance from the top tube at the lowest point, closest to the seat.

    How is the size? Is it correct?

    I just looked at the geometry chart for the Liberty CX. I'm 5'9" and the 54cm would be way too long for me. Of course, you're nearly two inches taller than I am, so it might work for you.

    I'm having trouble reconciling the 54cm size claim with what you're saying about "the seat at its lowest point" and what you said about standover clearance. That bike looks like it has compact geometry, so I would expect that if you don't have a problem with standover that you'd be able to get the seat height comfortable. Having to be on tip toes to touch the ground isn't really a problem (in fact, it's often cited as a sign of correct saddle height), but I wouldn't expect you to have to put the seat at its lowest position to achieve that. Can you post a picture?

    What are you talking about? The seat is not at its lowest point.

    It is at the lowest possible point. Those two screws for the water bottle mounting have washers (or something liek that) inside the tube that prevents the seat from going any lower.

    A generic seat height trick is to put your cranks parallel with your seat tube. Put your heel on the low pedal. Your leg should be at full extension (but not locked knee) if your seat is high enough.
    That sets you up with a pretty basic starting point to ride around and fiddle with the rest of the adjustments until things are comfortable.

    It doesn't look bad the way it is. Your foot is quite a bit farther forward on the pedal than I would want.

    That must be one really long seat post to be reaching the water bottle bolts.

    If the seat post is bottoming out, and it too tall, then you can cut it to get height that you need. I've had to do it before, and expect to do it again..

    Size seems about right. Adjust the saddle position/seat height depending on your riding style/position preferences.

    I'd buy a shorter seat post before I'd cut one. If you do cut it, remember to adjust the minimum insertion point accordingly.

    I've corrected this and use the balls of my feet instead of the arch to pedal. It improves things quite a fit and feels quite a bit nicer.

    Old school .. stand flat footed, straddling the top tube, ahead of the saddle, (not sitting on it)
    then lift the front wheel off the ground, how far off the ground is the wheel?

    Purposeof bike , Cyclocross racing or JRA , it's just transportation?
