Hi Lucky.........gosh I thought I was short at 5'4" I ride a 48. I had my bike custom built by Serotta and of course had one of their bike fits. If you have a Serotta dealer in your area they will do a bike fit for you and you can go from there.

You'll find out IF you NEED a custom built or if you can by a frame off the rack so to speak. Sounds like you've tried all the tweeking of seat and ect....I can only add that there is IMHO nothing sweeter than the feel of steel!

I wish you luck and post back what you've decided.
