Any question answered...

I wouldn't think it would matter on the road (ie riding round ldn), but surely aerodynamics is important on the track as you're actually hitting a decent speed.

Cheers, that's really helpful.

and while you mention it, I have actively avoided the east end ever since I moved to London.

I am now abondoning the cold windy climes of north west London and moving to Dulwich, does this make me a hipster?

Yes. Dulwich is now what shoreditch was in 1991 ;)
