Cannondale Super Six Evo

I think you’ll have to opt for the 52. Cannondale doesn’t make 51s.

I thought they did…http://www.ebay.com/itm/271412349579?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

I have a 51 cannondale supersix.

Oops, right you are. They make a female frame in 51.

I just noticed at the bottom of the ebay add it says that the frame is a 50cm not a 51cm. No idea why they would advertise as a 51cm in the title??? Appreciate the info.
