Thanks, everyone. I bought the Lifeline one from Wiggle, mostly because it comes with a set of 1/4" bits, and most of mine are 3/8". It looks fine in its smart little case. Jonathan PS: What are Chain Reaction like? I buy most of my stuff from SJS, because they understand touring bikes. Second choice usually Wiggle. But I've bought quite a lot from Spa Cycles: very knowledgeable, good on tourers and old bikes, good prices and sales, but hopeless at communicating unless you're prepared to do everything by 'phone: recognise the pattern?
