- Anyone using XTR 980 cranks with a single ring?
I am. I bought a triple. Pretty sure the double/triple have the same chainline. It doesn’t look great with normal chainring bolts, works fantastically though. You can buy tabs (like the ones that come with the double)to cover the outer ring but they are very expensive.Posted 6 years agoJamesDMember
I’ve got the standard M980 double chainsets, so no. Which incidentally is a different BCD (88 I think?) to the triple.
Also, haven’t really worked out the difference between the M980 double (bolts covered) and the M985 double yet (bolts showing)!
But anyway… I guess it’s these that Shaggy is referring to?Posted 6 years agoshaggySubscriber
The M980 (trail) comes as a double or triple. Pretty sure the crank arms are the same (standard 104bcd). Standard BCD makes it a better bet as a single.
The M985 (race) uses a smaller bcd (88mm sounds right), I think the chain line is different to the M985.
Shimano sell the tabs that come on the M980 double, in place of the outer ring- they are like the one James mentioned but match the colour of the cranks.Posted 6 years ago
