Most compact chainsets I have used have had the chain rub on the inside of the 50t ring when in the small cog or smallest two cogs.
Short chainstays makes it worse. I just don't use the smallest cogs when in the small ring.

Agreed. But if you read this thread the op had rub in the bottom 3 or 4. Spacers return it to normal. And shimano cranks have no rub at all!

I did read the thread (you have a reply right under one from me). I know the OP had rub in 3-4 cogs. I did not think that needed to be repeated. I was just saying that I think rub on a cog or two, with 50/34 rings and short chainstays, could be considered normal.

Next time I will either repeat the entire thread to prove I read it. Or I just won't post at all.
