I have a stubborn crown race I needed removing earlier this week so I could send my forks back (to the online retailer,) under warranty. Popped into my lbs to see if they could do it the following day, explained the situation, they did it there and then. Free of charge. Because of service like that, I try to use them as often as financially viable.
A previous lbs (in Bangor,) were great as well, always sorted me out. Took a bike in to get some bearings fitted and somehow walked out the shop having spent £1300 on a new bike. Not sure how that happened….
