United Kingdom - cycling-related things to do in London that don't involve actually riding?

I'm currently in London visiting a friend who has a two week old baby. I was planning to go to the Rapha Cycle Club to check it out. It looked like a cool concept. Also, none of the bike shops in Miami carry Rapha apparel. Turns out, the Cycle Club is no longer open. So, I'm tired of staring at the baby and want an excuse to get out of the house -- what are the best bike shops in London? Which ones have the most variety of apparel? Or do you have suggestions other cycling-related things (other than actually riding) to do in London?

I should also mention: I'm interested mainly in road riding.

Pretty much any of the Evans Cycles stores (located all over London, seemingly a couple of blocks away from each other) has been known to keep me interested for several hours. I'm utility cyclist myself, so I don't know if it would work for you. They do mention that their Waterloo Cut store is specialised in road bikes.

Last time I was in London I bought a couple of Foska jerseys (London road map & Marmite) at the Evans by the Embankment tube station. I will be there week after next and expect to buy a London Pride jersey, because my brother worked for Fullers brewery.
Another thing you can do in that area, is sit outside the pub at the N end of Blackfriars bridge and watch the bike commuters.
