Hi Folks

If you're on the small chainring and the chain is rubbing against the inside of the large chainring (typically when i'm in the last 3-4 higher cogs), can anything be done to get rid of the rubbing noise?

Thanks

Yes, shift gears.

you should be in the bigger ring if your chain is rubbing it.

or stop buying compact doubles

Do you mean to say that this is normal?

Depending on your chainrings, it could just be that one of the rings is mounted the wrong way around. That is, the rings may not be symmetrical from side to side, so they're closer together right now than they're supposed to be. I had the exact same problem after getting my rings replaced recently and just noticed that last week. I turned the smaller ring around and the problem was gone.

No way this is normal. Are u sure it' rubbing against the big ring and not the derailleur's cage?

Yes, i can see it not rubbing against the cage and the noise is different, lower pitched.
I don't think it's normal either. I would expect this in the last cog, but not in the 3rd cog (high).
I recently replaced the chainrings, same dimension, manufacturer writing facing outwards.

I suspect this IS normal, but I think it's a combination of short chain-stays and compact doubles. What bike are you riding and size are you riding?

Pinarello Angliru 2007, size 58cm. Isn't she a beauty?

Off topic, but why those pedals on such a beautiful bike?

looks like a compact double to me.

if it is rubbing, you're in the wrong gear.

xfimpg

Thanks.
I'm selling the bike so I moved the pedals to my new roadie and put basic pedals.

You're right on, compact double.

So compact doubles are known to rub a lot, is that correct?

My triple makes absolutely no noise, i barely ever use the trim.
