    Plastic chain guard

    This plastic chain guard seems to actually keep the chain in place. I've seen some Specialized kids bikes with it, and shown below is a k2 Attack.
    1. is there a different way to increase the chain tension so I don't have to rely on this?
    And/or
    2. I have the inside and the outside plastic ring, but there holder pieces have cracked--any ideas on how I could put this back together?
    (A new crankset is not in this bike's future.)

    Would love some advice,
    Ridwan

    Doesn't look like a replaceable chain ring, so narrow wide is out as a solution.

    Something like these can help to keep the chain from dropping on the inside:

    For a super cheap version, I've seen people make them out of old reflector mounts.

    Failing that, you could look for a cheap front derailleur and just use a small piece of wire and the adustment screws to center it over your ring.

    Here's an example photo I found from a Google image search -- basic idea is that it keeps the chain from dropping off towards the frame.

    Pretty much small piece of plastic with a similar profile would accomplish the same thing.

    As a bodge you could epoxy some washers onto the chainring

    We used something like this on my son's bike.

    Note, we bought it much cheaper than that, it can be found.
