    weird wheel things around chainring

    I keep seeing on pics of FR and Dirt Jump bikes these small round (usually orange) things that look like small wheels around the chainring. There are normally i think 3 or 4 of them, and i was wandering what they're called and what they do. Thanks for any replies,

    Silverfox.

    Possibly rollers for a chainguide, although there're typically only two (this bike has black ones):

    i think you are seeing mrp chainguides. and they normally have 2 rollers.
    edit: okay mrp chainguides have both black and orange rollers
    Trance music is okay...
    Drum & Bass is way better

    would recomend an e.13 SRS or DRS. I have the SRS and it takes all worries out of your head about losing your chain. If your riding style can constitute using one I would reconmend
    "I'm; young enough to know the right car to buy yet grown enough not to put rims on it. I got that 6-deuce, with curtains, so you can't see me and I didn't even have to put tints on it."

    They are used to keep the chain tension high and hopefully stop the chain from dropping at high speeds. Really useful on suspension designs that produce a lot of chainslap
