The seller has the size incorrect. A 23" frame equals 58.4cm. I do agree with others that it may be a bit small for you; I'm 5'10 with a 30" inseam and feel most comfortable on a 23" (or 58cm) frame (c-t). It looks like a nice bike however and definitely worth a visit if close to you. Test ride it and if it fits and the price is reasonable it would be worthy of consideration IMO.
