Witcomb Cycles

The website has a pdf of their repair prices but expect to pay slightly more when you go in as the list seems to be a lower end guideline. Also their parts are vastly over priced, they tried to charge me 20 pounds for a 6 pound shimano BB.

Hmm... I did ask them a while ago about headsets and they said around £30 for the part and installation, though the website quotes £25 just for the fitting? Maybe it was my womanly charms... (would make a nice change from the reaction I got from Brick lane bikes a couple of years ago which was basically 'you can't build a bike, you're a girl' though I think they've managed to curb their sexism slightly since then.)

Not good news about the bb, maybe I'll do the parts sourcing myself.
