I've always found Berkshire Cycles to be good, and bought numerous leisure bikes from them but I've bought my road bikes from Cyclezone (Crowthorne) and have found them to be fantastic at all levels. Only LBS I've found to be rude was
AW Cycles in Caversham, just so far up themselves. Told me I wouldn't ever need a CF bike as I could never do it justice when I made an enquiry and dismissed my notion of getting one as money wasted. I have a CF Ridley bought from Cyclezone two years ago which is the 'dogs whatsits', and it was discounted to boot. Not really visited
Evans much as parking is complicated
