Many folders come with a bash guard instead of a chainguard. These two were posted to the forum not long ago.
You have to count the teeth of your front chainring, and make sure the distance between bolt holes (the BCD
) is correct.
You'd be making a choice between protecting against getting dirty from an exposed chain along the top of its travel (using the chainguard the bike came with), or protecting the bottom of the chain (or things like carpet that it may rest upon).
IMO, most folders come with bash protectors. Maybe because most come with rear derailers. (Shifting a rear derailer causes chain movement that can/will cause the chain to jump off the front chainring when there's no front derailer to act as a guide.). The bash plates are on both sides of the chainring to act as a chain guide, keeping the chain from jumping off. It also acts as a bumper when the bike is folded, so those people never think about resting the chain on the ground.
You might be able to use a bash guard with your chain guard. You'd put the BG on the *inside* of the chainring (requires removing the crank from the bottom bracket). There may be enough clearance between the chainring and the stock chaingaurd for the BG to rotate.
If you really don't want to get grimey from contact with your chain, you could use a freedrive
chain cover. That may work with a bash guard. (I haven't used one of these. I've read mixed reports. People seem to love these or hate them. This doesn't solve your problem of resting the chain on the ground. It may solve your problem if you don't like the idea of removing your stock chain guard. Your choice of chain lubricant would affect how dirty you get from an exposed chain. Wax-based lubes like White Lightening don't seem to transfer as much nasty grime as oil based.).
