Ribble have a good reputation over here for respectable bikes but I looked at their website a couple of years ago and wasn't impressed with their prices. PBK and although I have ordered a few parts from them- I find that they are out of stock of too many items I want so it has to be a good price for components for me to use them. Merlin Cycles and if it is Mountain bike then they are good. They moved into road parts a few years ago and stock a lot of wheels at good prices but never used them for road. Chain Reaction Cycles are my favourite and I use them. Communication has always been good and delivery spot on but that is in the UK.

But I find that my LBS can always come very near to the Internet prices so I rarely have to go elsewhere.
