I've never used Ribble but a lot of other riders have with satisfaction as noted above. I have ordered from Wiggle (don't you love these names?) several times and have been very happy with the prices and delivery times. Wiggle will quote in USD and shipping is free with a moderate minimum order amount. My son-in-law has also ordered from Chain Reaction Bikes and ProBikeKit and been happy with their prices and service so you have several choices.
