Something else to bear in mind. I'm looking to buy a kickstand for my bike. Cube make one that is specific to it & it only costs €23. However, I can't source it locally and the cheapest postage I can find is €17! That'll be the day. So if you're buying a bike in the UK make sure to buy any of the 'extras' there too. It'll save you shedloads in the long term.
