Thanks for all y'alls help...

As far as the pink motobecane, it's 51cm and I believe I need a 54cm or a 17-17.5" bike because I am 5'6.

I am still kind of interested interested in the univega, but I have a few questions...

What does a claw RD hanger mean?

What is cool about thumbshifters?

and, What is XC Pro?

thanks again,
Wayne
