I really like RF cranks (especially the CINCH interface) and have had about a dozen over the years with excellent results (except pre-CINCH SIXC cranks which failed at the carbon spider-twice). After a few years without a new bike build, I built 2 boost 29'ers this past year, both w/ CINCH cranks and shimano 12 speed drivetrains (cassette and chain). In BOTH cases the boost, shimano compatible 32T RF chainring was really loud in dusty conditions. No chain suck or retention issues, just LOUD. Sounded like sandpaper. I am pretty meticulous about drive train cleaning and set up. I thought about bringing a tooth brush to clean my drivetrain mid-ride. Changing to a Wolf Tooth ring (32T, boost, shimano 12 speed compatible) fixed the problem on each bike. Anyone else run into this?
