    I don’t know about Rotor rings but Biopace (also oval) are OK for singlespeeding as they don’t make the chain tighten and loosen much at all. So they don’t make the mech move back & forth.

    I run a 1×10 drivetrain, use a bash guard and a Jump Stop, never had a problem droping the chain until I started using a Rotor Q Ring, only does this on rough decents.
    I have read that a clutch style rear mech will reduce the chances of the chain getting dropped as he mech will not flap around on the rough stuff.
    I was wondering what effect the Q Ring (if any) will have on the clutch mechanism, as the rear mech cage moves forward/back due to the oval front ring. Will I notice a pedalling resistance, probably not, but just wondering.

    Thanks

    The long cage rear mech probably deflects about +/-5mm

    I can’t find the links quickly but there are several people using clutch rear mechs and offset rings without any issues. The chain growth is small as BigJohn says- if it works with singlespeed then it would look to be fine with a clutch mech too.

    Is the Rotor ring the singlespeed version? If not this might be an issue helping the chain to drop a bit.

    Thanks, pretty sure its a singlespeed ring but will check.
