Dumb question I know - but what is the difference between them? Is there any? Also, I've just been checking out importing a 6pack into the UK - does a 4% frame charge sound about right for a frame charge? There charging over £1500 in the Uk and good second hand ones arent easy to find. I've got about 3 weeks to get hold of a frame and I'm starting to panic now because I cant find any that I like, idealy I'd like a 6pack but have been thinking of a Heckler( I know totally diff bikes!), any idea's? help!!!:madman:
