I have an XTR M960 crankset with a 32T middle ring and 44T big ring, I am a little unsure which Rohloff cog I can use with the chainrings. I think if I use my 32T ring I would need a 13T cog to comply with Rohloffs permissible sprocket ratio. If I did use a 13T cog I think it would mess up my chain line. If I use my 44T big ring I could use a 17T cog which would work but again I don't know if my chain line would be off. Anyway if you have any input on the matter it would be greatly appreciated, I really don't want to buy a new crankset. Thanks.
yes, the outer ring is the correct line. A 17t rear is no problem and should wear a little better hopefully than the standard 16. If you are getting a new set, see if the supplier can substitute the 16 with a 17 as they aren't cheap sprockets.
Also worth noting larger rings / cogs result in greater drivetrain efficiency. Probably not enough to notice, but definitely enough to measure.
Question is, does the (also minor) weight savings and ground clearance of smaller rings/cogs outweigh the increase in efficiency?
To maximize drivetrain life, a 40T Surly stainless steel chainring ($30) plus a 17T Rohloff cog will last a good long while.
