    Haven't noticed any issues, but I'm rarely on the 10t cog, and haven't been on it at all in rough stuff.

    No slap here but I'm on a Calling which doesn't have the chain slap problem to begin with.

    Gotcha, yeah Evil said I would get some so close to the swing arm. Just wondering how bad it might be. I really cant push a 32 oval where I live, not saying impossible, just not practical for me.

    I'm running a 28t elliptical ring with an E13 cassette on both a FMB and a Wreckoning so 28/9 is my tall gear. There is some contact with the chain stay guard in that gear near the chainring but I don't notice it at all. Just looked and there's no sign of contact or wear on the guard. I haven't noticed any chain slap but I wouldn't say I'm riding chunk in the tall gear, and rarely in that gear at all.

    Being that there is some contact with the rubber CS guard, I'm not surprised they would advise against it. It's been my experience on both bikes that its not a problem and I'm not bothered by it. I really appreciate the small ring towards the end of a 5k climbing day which is pretty often.

    Yeah man! Thats what Im saying. Been pushing a 30t, but really would like to try an elliptical for amusement. Do you actually feel any benefits?

    Not a huge difference but I do feel it's better on steep, low cadence climbs. Can't tell it apart from a standard ring anywhere else.
