Any question answered...

BLB or Condor. *

You've got next to no chance of getting Condor to fit it soon though. IIR there is a waiting list on repairs/workshop.

Whereas BLB I think have a first come first served policy.

Pretty sure both are open on Sunday.

Otherwise i'd have thought all of the Evans' are pretty decent and will be open on a Sunday - the one near Spittlefields, but not in Spittlefields is the one you want.

Thanks for this. I pass Condor on my ride home, so I'll drop in tomorrow to ask. I'm quite obsessive about things being done properly (which is why I do almost everything myself), but I don't have the tools suitable for doing this job well.

Condor quote £20 with an additional £7.50 if you require reaming. Seems reasonable to me, seeing as I'll have some sort of level of guarantee that my shiny new Campag Record headset won't wear prematurely.
