I understand that the increased forces on smaller rings can increase the chance of chain suck. In my case this always and only happens eventually on the granny, to be fair once components are worn. However I must say it has been consistent to the point where it has always occured at the same point on some of my local rides last year and this, a quick clean and I’m off again.
Weird I know. I think it must be down to the chainline on my Marin but believe increasing the size of the granny may help. In any case it’s not my main reason for change.
Thanks for the answers – useful, I’ll be trying 24+36.
