London shop for women's road bikes?

I can't tell you anything about women's bikes but I do know that Condor Cycles on Gray's Inn Road is a fantastic shop and that they will happily spend a couple of hours fitting you on a jig and working out the best choice of components for you. Go on a weekday if you can so that you can be guranteed their full attention.

Seems crazy that you should be struggling with this in London of all places. There is a Spesh concept store though:

Spesh seem good at the female stuff, they apparently have an entire product team devoted to womens-specific kit, and are one of the firms that don't simply 'paint it pink and give it a silly name'. They'll do a good bike fitting as well.

Hi. Try Sigma Sport out in Kingston. They specialise in higher end bikes and stock a large range of brands. They definitely have the Specialized women's range and possibly the Trek WSD. Direct train from Waterloo (Zone 3, I think)

I'm not sure if their range on show goes that high but I always find the family run Simpson cycles in Kentish town very helpful.
