chain rub on front chainring

[madscot13]

How do i adjust to get rid of this? It is not on the derailleur it is on the chainring itself. I can't really say I've had troubles shifting but I'm not terribly sensitive to those things- or things in general.

Which front chairing/rear cog combinations do you get rubbing on? Small front-small rear there is often inevitable rubbing. Only thing to do is avoid those cross-over gears.

It is middle chainring with the smallest rear cog. chainrub with the second smallest rear cog is not noticeable. i tried to increase the H limit screw but that only seems to make it rub in the back.

I should also say i have a triple.

There is no way to eliminate it. Just avoid that gear combination. That's actually somewhat unusual on a triple, but very common on a compact double. Depends on the difference in the chainrings and the bike geometry/chainline. Short chainstays make it more likely.

thanks Deb. It is sort of strange because it is a new occurrence, or at least I think it is. I'm sure i would have noticed it before.

Deb, is it a bad practice to use all ten cogs with the middle chainring if I'm not getting any noticeable rub?
