    456c Chain Ring eating into the frame?

    I have a 456c frame with a SRAM x7 crank and noticed that my chain ring looks to be eating in to the frame. Took it to the local bike shop to get a spacer for the bottom bracket so I can make the chain ring sit further away from the frame but the guy said it was the chain eating in to it when going from 2 to 1 up front.

    I'm wondering which is more likely of the 2, would it be better to go to a 1 by and how hard would it be to repair the damage to the frame or what I could do to limit further damage. Added some pictures.

    Looks like you are getting chainsuck, partly from the chainring being worn. And not being sensitive to the chain jamming when it sucks.

    Contact Ruckus Composites about carbon repair http://www.ruckuscomp.com

    A spacer will not move the rings outboard. Need to remove spacers from the non-driveside to do that.

    The trouble with common sense is it is no longer common

    Get Amazon.com: Lizard Skins Carbon Leather Chainstay Protector (Black): Sports & Outdoors and maybe some helicopter tape as well. I don't understand why more people don't go to extreme lengths in order to protect their multi-thousand dollar bikes. I bought a 2012 Slayer 70 last year and I didn't even consider riding it until I had covered every single area that could possible sustain damage. So far, its been working great 4

    Yeah, wasn't too sure myself looked kind of deep but oh well. Have an idea or 2 to minimize further damage till I can get some work done on it. Gonna prob end up with a 24/36 chain rings to replace the old worn out ones. Anyways, thanks again appreciate your take on it.
