Hi,

Given your height and inseam, I would guess that your current frame is not sized properly. I used to do bike fittings at a large shop in Southern California using a Fit Kit to baseline a rider. However, I wouldn't want to guess a frame size or a top tube length without seeing you on a bike.

Two recommendations:

1. Go to a reliable bike shop that primarily deals with high-end road bikes and get a professional fitting. If you can't find a shop like that on Hawaii, maybe you need to treat yourself to a trip to the mainland.

2. Use an old steel road frame with long dropouts for your fixed gear bike. (Don't buy the frame until after you get a fitting.) There are also some framemakers who are building road bikes for fixed gear use. Going this route will keep you from having to get the fork drilled (among other things.)

Hope this helps and good luck.

Thanks.
