Jessie - just curious how tall are you and what is your inseam? Ridley sizing is off the wall - on their website it says if you are 6 feet tall your inseam should be between 36 to 37 inches. Even if the stand over height is irrelevant those are some long legs suggested by Ridley!
Yup - Ridleys have very long seat tubes and and short top tubes. I am 6'1/33-34 inseam and the bike fits perfect for me. Not a ton of stand over but enought. BTW - I think the Ridley Geometry on their site is off. They have the Supercross and Crosswind listed as having the same measurements. I have both bikes in size 56 and they are not the same. The Crosswind has a shorter headtube and seattube vs the Supercross.
