Here's some you may find helpful..all in the UK. "Wiggle" is known for it's fast service and has a good range. SJS cycles has a comprehensive range but postage tends to be pricey on small items. Edinburgh bike co-op is also good and their range of "Protective" clothing is top notch, again they sell probably the cheapest basic tourer there is. Spa... is a specialist in touring products and has a great reputation. Good hunting.
