Back to those XTR cranks for a second...in summary
T says 2006 XTR are great but use only Shimano chainrings
HD says 2006 XTR chainrings are soft as sheet
Therefore i conclude XTR cranks aint worth investing in.
FWIW, i need new chainrings for my 2003 XT drivetrain and thought at the prices Torpedo7 list the 2006 XTR cranks at I should upgarde. Hence 2007 XTR's are out of price range (and I dont like them)
IMHO The 06 stuff sheets on the 07 for asthetics!
Back to der drawing board...
