What's the difference between Shimano road groupsets? -

Like its main competitors SRAM and Campagnolo, Shimano has a hierarchy of groupsets with levels offering different weights, number of gears and – of course – prices!

It’s important to remember that while each groupset name maintains its place in the hierarchy, they are usually updated every few years. So, for instance, when Dura Ace – Shimano’s top-of-the-line groupset – was launched way back in 1973 (as Dura Ace 7100), it was 6-speed; it is now 11-speed (Dura Ace 91xx).

I will try to keep this list current, please give me a shout if I mess up!
