do we need so many gears?
i have 27 gears and im sure you could get 24 gears with the same hi-low ratios, and smooth up or down change and end up with a stronger chain.
there would be better mud clearence and lighter cassette.
i cant seem to see the advantages of so many gears.
Will bikes now with the new sram xx have an even thinner chain.
anybody else seem to understand my point of vue or can anyone enlighten me why 9 cogs at the rear seems to be the norm.[/b]

Nope. So if you like it???... If it is working and you have had no problems I can't see a problem really.
SRAMS lightest rear cassette actually has 10 cogs.

Surely it depends on where you're riding... up Leith Hill, granny ring and big slow gears, riding down the trails middle ring and coming back on the roads large ring and smallest/fastest gear on the back. I use the full range on a normal ride.

theoretically, 8 speed is stronger i suppose but then, ive never broken a correctly set-up 9 speed drivetrain.

It depends on the quality of the chain and it's design. The most important factor is tensile strength. However, no matter how strong a chain is, if the connection pins were inserted wrong....SNAP!
Having said that, I've never snapped a 8 speed chain, but snapped a an expensive Shimano HG93 on a red run.

If you had an eight-speed cassette with the same 11 and 34 ends as a nine-speed, then you'd have a big jump somewhere in the range. many of us don't like the big change in pedalling speed that would require.
It was certainly a problem in the 7-speed days; Shimano's 13-30 cassette was gappy as hell.
If that doesn't bother you, then there's no reason why you couldn't use eight-speed stuff, except for the minor problem of finding good quality eight-speed parts.

Big jumps in gears can slow you down too much if you are in a hurry e.g. xc racing. Generally I guess we could manage on less though.

Doth the winged life destroy,
But he who kisses the joy as it flies,
Lives in eternity's sun rise. (William Blake) |

We have so many gears, compared to a car, for example, because humans aren't as powerful as cars, so we have to be as efficient as possible, by having lots of different gear ratios.
