Could someone give me the benefit of their experience please . i just bought the coiler dee-lux ....way cool..... after reading a lot about which frame size to go for on this site i opted for the 17inch as opposed to the 15 inch ( 1 am 5ft 8 ) as i figured i would be doing more street riding than extreme mountain descents. however i have read you should have up to 3 inch of space between the old chap and the frame but i am practically sitting on it. Looking at the spec difference between the 17 and the 15 frame it seems that the only size diffs are the top tube is 1 inch shorter in lenght and the standover is 0.5 inch shorter 32.7 to 32.2 so does this mean even the smallest frame would only give .5 inch of clearance ??? i am not a dwarf and dont have stumpy legs so is this just down to the style of the bike ? the shop said its fine but they would as they only had a 17inch frame..........
