I have the SRAM Red cassette on a Mavic R-Sys wheel. The cassette is tight but rocks side-to -side ever so slightly. I have found that the cassete works loose and starts getting noisy as one can imagine. This last time I torqued the lock ring to 40 Nm as specified, previously I just tightened it with out a torque wrench, hopefully it will stay tight this time. Anyone else experience this?
