DirtDiva, oh that's very interesting to know about Giant, thanks.

The Scott option looks good too, but no shops here stock them - or seem to only supply the higher end carbon models. Aaargh - I wish I could try that bike out

I've been back to the Bianchi dealer this morning - they have a '06 Dama Bianca Veloce reduced to £700, but it's one size too small (albeit only too small by 1cm ish). They've said it's possible to tweak the reach with a larger stem. I can see in the brochure the 51cm frame fits my bikefitting diagram more accurately - so should be patient and wait to try the '07 model (which is £200 more, with Ultegra).
