I’ve never managed to damage a chainring that way, the chain does cover the teeth so there’s only a risk of maybe bending it… But they’re mostly pretty tough. On the other hand, landing on the chain tends to be less pleasant than a bash or taco, they slide less well and the impact’s orrible. Wouldn’t like to swear by it but I reckon I’ve crashed because of catching the chainring, where my poly bash would have slid. (I like rolling off steps and banks and stuff, don’t know why, every so often I regret it 😉 )
Question… Why a taco? Why not just a bashring? That’ll give you a chain retention bonus, and is barely any heavier. And if you’re bb mounting, tacos can be a pain, my old XCG used to merrily rotate around the shell til it jammed in the frame.
