The stand over heights are quite tall and can be problematic. I ride a size 59.5 or size 60 road bike. Yesterday I took delivery of a size 58 Ridley X-Fire and it appears that it is one size too tall for me. When I straddle the bike I just barely clear the top tube. When I mount and dismount I have a hard time clearing the saddle with my leg. I am now offering my brand new, size 58 X-Fire frameset for sale at $1100 including continental US shipping and insurance.
