Stone 110BCD Round Chainring for SRM Power Meter Cranksets (Shimano FC-5800/6800/4700/9000, 42T–70T, 1X)
Check Your Bolt Distance Before Ordering
Both PM7 and PM9 cranksets are produced in two versions: one with a 106.5mm bolt distance and one with a 110.8mm bolt distance. Simply knowing whether you have a PM7 or PM9 is not enough to choose the correct chainring.
You must measure your bolt distance and order the chainring that matches it.
