a.e. wilson in peckham are cheap and all down to earth
paul's custom cycles also in peckham i've had good experiences with
also A&W Cylces (http://www.allinlondon.co.uk/directory/1284/2883.php) is really nice since it's just some old dudes in a proper dark, shabby shop. i find that they're really good for finding parts for old bikes which have weird sizing and dealing with older bikes in general.
although they were confused by my TRP road lever breaks (which don't have gear shifters in them) so i'm guessing maybe they're not ones for the modern world.
