I'm currently running a 12-27 cassette and a single 110mm 41t chain ring. I'm trying to find a properly fitting bash ring, and not having a ton of luck. Anyone know of an appropriate product?

If this is a double crank, you can grind the teeth off of a larger chainring and use that as your bashring. I've seen this done on cyclocross bikes and it can be made to look very nice as well as being functional-

It depends what you want this guard to do. If you just want to provide a little protection for the teeth, then either a ground off chainring, or something like Salsa's crossing guard will work. You want it sized a little bigger, I think the Salsa works for up to 44 teeth.

If you need serious protection, more DH style than cyclocross, well, I don't know enough to help there.

BBG Bashguard. Makes a little of everything. They have a 42t that would probably work. They will also do custom if you want. Cheap too.

Oo, that looks great. Thanks. I don't need anything crazy sturdy, and I'd like it to be fairly light, so that's perfect. Just don't want to bend the chain ring and screw up the bottom bracket going over a small log or something.
