    plastic thing under cassette

    went into the garage to get a beer out of my dedicated beer fridge and noticed that my fiancee's target bike (one step above a wallymart bike) has a plastic thingy under the cassette.

    what the hell is it, and what the hell does it do?
    how durable a bike or component is usually has a lot to do with how heavy and ugly it is.

    It's a "Dork Disc".

    It is to prevent the chain from wedging between the cassette & spokes in case of a chain derail @ the cassette.

    It's probably a good thing to leave on @ least until the rear derailleur is debuged.

    It's a Target bike and therefore not totally out of place. If you do remove it, at least make sure the limit screw is adjusted properly so the chain won't get sucked over the top of the granny cog and into the spokes or you'll have some 'splaining to do.

    As I said, leave it there until the rear deraileur is sorted out.

    It isn't hurting anything & the only reason my 2 bike are sans "dork disc" is that it broke on one of them & i changed the rear wheel to a disc hub on the other so the original DDwould no longer fit..
