I live in east Manchester and there's one virtually on my doorstep, but it's a bit pricey and the last time I took a bike in there it took them two weeks to fit me in for a few small jobs (bar tape, bb and crankset replacement. I think it'd have taken longer if I hadn't gone in to enquire why my bike was still by the door, exactly where it'd been left two weeks prior) - I just wasn't experienced enough to do them myself then. Seems more geared towards new bike sales anyway - shop is full of them and there's been a Charge Plug 1 in the window for ages. They have signs up stating they offer set-up services for bikes bought online too. I heard on the grapevine that the shop had a mechanic that only visited once weekly but I don't know what to make of that.
The next nearest by I've used once - asked them to do some jobs including a chain, they said okay and quoted a price. They call up telling me my cassette needed replacing and they'd also serviced my bike (when questioned they said it wasn't a full service per se - if that's so why isn't my headset notchy any more?!), and they were now charging me £25 more than quoted. I said I didn't want that doing, okay, they took the cassette off again but I ended up paying for the service seemingly as the labour etc added up to the original quote. I asked for my old cassette back and it turned out they'd binned it when they changed it without consulting me, so I ended up being given a free new one. I decided I wasn't going back there again if I couldn't trust them to ask me before doing anything I hadn't really asked for.
Considering my experiences, what LBSs charge for labour and the lead time on jobs, I'd rather learn to service my own bikes, as I am doing.
A Halfords Cycle Republic opened recently in Manchester but I've no reason to go in there, can't comment on it. If they sell Apollos in there then I'm never going in on principle.
There's an EBC but all they seem to do is sell hybrids and such to Didsbury commuters on B2W and a few own-brands (I really don't see Revos that often, a lot less than I used to) - that said they were pretty helpful when I ran in one lunchtime on a Pug with a dodgy bottom bracket, more out of necessity than anything.
And Evans is just too expensive - bottom brackets are £10 or £15 cheaper on Amazon, and they're far more likely to have the right size, whereas Evans have about five on the shelf in any size combination at all. I seldom find what I'm actually looking for in Evans, either they don't have it or it's just too pricey.
I'll stick to DIY I think.
