Chainring Bother

Just put brand New Sram red Chainrings onto a Force crank, but it does not line up with the chain when in the large ring. Chain is new and crankset is sitting properly within the bottom bracket, but chain skitters along the teeth.

Any tips?

    Fitted the chainring the wrong way round ?
    Whip one off and look at either side, one side may be machined differently to accept the chainring bolt...nuts, if that makes sense.

    Nah, pretty difficult to do that with Red chainrings. It's quite obvious which way round they should go. It's as if the chainring is running too close to the BB.

    things i'd check...

    is the front mech set up correctly?

    which rear sprocket(s) does it happen on?

    is the chain knackered?
