the ridleys are BEAUTIFUL bikes. saw some being built up last weekend and they are truly gorgeous. but you would need the 41. i am around the same height and i ended up with a specialized crux in 46. i think standover will be an issue wtih most frames - i can stand over the bike wtih my feet flat on the ground... it's just that there is some contact then between my body and the frame. practically, this really isn't a huge issue. at no point in a race will you be standing over the bike, and for starts and such it's not wildly uncomfortable. YMMV, but i would definitely advocate trying some out if you can
