Just popping in to be an obnoxious know-it-all...

Trek420 found the Surly LHT to run large. She generally fits a 46cm frame, but the 42 cm LHT fit her beautifully.

I have a 52 cm Surly Cross Check, which fits me just as perfectly as my 53 cm Waterford X-12.

Surly is a product of/owned by QBP, so your LBS should have no difficulty ordering one in your size. (no non-comptetition issues with Trek or Specialized or whatever.)

There is a Surly CC and LHT owners website that might have some nifty info you can use: www.surlyville.net At the very least it has some yummy bike porn! (pics)
