So looking at the costs in more detail then, as a rough guide a Ti or a Reynolds 953 frame is going to be around the £2k mark give or take a few quid. That is irrespective of its made in the UK or overseas.
So which industry is it better to support, the UK or overseas?
Having worked as a buyer in a former life of course the overseas frames will be cheaper to produce for all the reasons already mentioned, yet they retail for the same price as a frame made in the UK. Again, as has already been mentioned, profit margins are the aim of the game for the people that supply them.
