I have 2 bikes with 9 speed Tiagra, one with 10 speed 105, and the latest addition has 11 speed 105.
My preference is for the 9 speed Tiagra. I am not Bradley Wiggins so I could quite happily have 6 cogs at the back, as long as they ranged between 10 and 32 teeth (some big long climbs around here!).
The more cogs at the back, the thinner the chain has to be, and the less miles it will last. Same for the cassette and chain rings too. And there lies the advantage - for the parts manufacturers and bike shops!
I am trying to find a triple, 9 speed crankset for a 7 year old road bike and it's not proving easy... They want us to "upgrade" which will of course require new shifters as well as the transmission parts.
Much the same here. I've one with 10 speed Tig, and another with 10 speed 105. Importantly, both are now on the same cables, and they don't feel any different. My preference is the Tig because of the aforementioned lever throw, but in terms of efficiency and reliability of function you couldn't get a chocolate mouses fag paper between them.
