Scrod,

If I have a 27.2mm Seatpost, what size FD clamp do I need?

Long story short, I'm trying to reuse a FD from a bike that had a 31.6mm seatpost, it seems that the smallest FD clamp size is 28.6. Would this work for me? http://www.amazon.com/Shimano-Ultegr...d_rhf_se_p_t_3

EDIT: is this something for the mechanics forum?
