Ah, I see! My chain drops in between the chain ring and the chain guard...
so what you're saying is the chain can fall both sides??
if it falls inside, it just falls... and if it falls outside, it gets jammed up in between chain ring and chain guard??
I inspected further and I don't think my CCS can fit a double guard anyways. They chain stay is just too close (pics attached).
The gap on my Cross Current looked like the one in your picture. I removed the chainring guard, flipped it 180 degrees, and reinstalled it. It’s pretty easy to do and it reduces the gap enough that I have not had any issues with the chain coming off to the outside (which used to happen all the time).
@youth
I got the Deckas 130BCD!
What tools do I need to replace the chain ring?
5 mm and 8 mm allen wrench, crankset puller tool, torque wrench ?
Just the allen wrench and a chaining nut tool. No need to remove crank. If you're lucky you might not need the chainring nut tool (if you can loosen the chainring bolt without the nut spinning on you) or you might trying improvising with a large flat screwdriver.
Ah! Got it! Do you put any sort of lubricant on the chainring nuts when you put it back together, @youth ?
It didn't even cross my mind that the guard wouldn't be perfectly flat. Good thinking!
I put on the double sided chain guard ($25) last night and no drops on the ride in this morning. Anyways it looks like there are quite a few solutions posted in this thread.
