Wow - what a great table you have made. I found a 43cm Cannondale R800 (New old stock) w/ 650c wheels which fits really well - they might be still around someplace.

The most important measurement is reach (ie; the top tube length) - which is why she will need 650c wheels (otherwise the TT can't be made short enough and/or she will suffer from toeclip overlap). Just for reference, I am 5' 1" & have a TT of 48cm. So I reckon that quite a few in the table may be too long. Bike Friday are great - but probably out of budget for a new one - but worth keeping a search open on Ebay - or looking at their second hand ones on the BF website. Luna would be a great choice - they seem very experienced in building for shorter people.

Other things to consider are handlebars - have tried a huge variety & am now very happy w/ the FSA compacts - very short reach & small drops. Also sti levers - get ones that will either take a shim, or have reach adjusters to bring them close to the bar. Then all you need to do is make sure the wheels are very true so you can run the brakes very close to the wheels. Oh yes - and cranks are very important. I struggled to find 160mm - they are available in a variety of configurations from TA - & very pretty they look too.

Good luck
