I never got on with Richmond Cycles after trying in vain to buy some 29er tyres off them (them being a Gary Fisher 29er dealer, so one of the few people in the UK who could supposedly get hold of them at the time – none of the online people had them). "Yes, should get them for you by Tuesday, will call you back on Monday", of course never called back, and on Tuesday I give them a call, "should be there on Friday". After a few weeks of this, I realise that they basically aren't actually able to order anything and give up on them, what a waste of time. Filed them in my list of useless bike shops who are worse than using mail order, and got a tyre 2nd hand off a mate to last me until mail order places started having them. So yeah, might be worth popping in (they have some fancy stuff), but don't trust them to get anything that isn't in front of your eyes in the shop (or to be honest about whether they can actually get anything, or to chase anything up).
