What a complete waste of money these groupsets and the others like them are - these groupsets neatly define the marketing BS of the cycling industry, and all that is wrong with the cycling industry, the profit margins on these 'higher end' groupsets and bikes is significant, you only have to look at the price gouging that has been going on with the massive percentage discounts now being offered on bikes across the board to see how greedy the industry got, and equally with money draining out of it now due to the economic downturn how the venture capitalists are selling off/shutting down bike brands. That aside great content presentation as ever by Warren
