The double and triple m980 trail cranksets use the same arms, the difference is in the chainring configuration so it should work fine. Keep in mind you are going to have to find a single speed ring that mates properly to the crankset and is the same width as the OE ring. Also the XTR crankset uses a non-standard chainline so rear cog spacing could be an issue.
