I googled, I searched, I called Shimano, nobody knows.
The only thing I found on here is, that the Race are 3mm narrower than the trail version, but that's just posted by a user and nowhere confirmed.
Shimano themselves could only tell me that it is 133mm from crank arm to crank arm, right at the spindle, but not the actual width of the crankarms by the pedals.
Sram has all that info on ther website in a pdf file for each crank, even the x5 and x7.
Is there anybody here who has the new 2012 double XT crankset installed, or somebody who works in a bike store and could measure.
I tried to install Sram XX 156 and they don't fit, it is too narrow.
Sram XX 166 would fit, but I want to install XT on this particular bike.
Any info, help is appreciated!
