Shimano XT and SLX go 10-speed in 2010

With the launch of SRAM XX last year it was inevitable that arch rivals Shimano would soon follow suit and launch their own 10-speed mountain bike groupset.

 

 

 

Industry rumours suggested they would introduce the extra gear on their top-end group, XTR. But instead they've chosen to debut it on updated versions of Deore XT and SLX.

 

 

 

Shimano are calling their new drivetrain technology Dyna-Sys, and insist they haven't simply added an extra cog to the cassette. In fact, they're calling it "a whole new way of shifting." Both groupsets will get new cranksets, chains, cassettes, derailleurs and 2-Way Release rear shifters.

 

 

 

Only a triple chainset will be available (42-32-24T) ? an interesting decision, given that one of the main perceived advantages of a 10-speed cassette is that you can ditch a front chainring yet still retain an adequate number of gears.

 

 

 

The Big S say that having a wider gear range at the back, more closely spaced gears at the front, and improved rear mechs and shifters, creates smoother and more intuitive shifting, more efficient and powerful pedalling, and allows the rider to stay in the middle and largest chainrings for a higher proportion of the time.

Jipee....so now we have 30 gears!  Any benefit as to 27 of them?
