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):

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

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
