Does chain suck still exist?
A few years ago I chewed a mountain bike frame when the chain jammed between the chain rings and frame. The chain came off when I hit a bump and had nothing to do with adjustment. I notice some carbon road frames have metal plates protecting this area and some don't and was wondering if it is really a problem with the latest equipment? Also, was it ever really a problem with a double chain set?
Just wondering

A properly-adjusted FD should eliminate any chance of dropping a chain on the inside of your small ring. There are devices that you can attach to be 100% safe against this also.
Chain suck primarily occurs on mtn bikes due to the excessive grime and gunk that you can pull up on the trail. I've never heard of it being described as the chain being jammed between the chain rings and frame. This is more of a misadjustment. Chain suck is when the chain tries to wrap itself around your rear cog due to not being properly released from the drivetrain - again primarily due to the links getting as gunked up.

Define "chain suck" for me. There are two quite different conditions that are commonly referred to as chain suck.
The original was a mountain bike thing. The chain would ride up the back side of the granny chainring and jam against the chainstay. Many people call throwing the chain off to the inside chain suck.
Both are common. Neither is normal.

I define chain suck as the chain getting caught between the granny ring and the chain stay, normally under full pedal power and normally with enough force to damage the frame

I've never heard anyone refer to dropping the chain as "chain suck"
I think we've beaten "normal" to death in the other thread.

I think I've experienced chain suck on every mountain bike that I ever owned - usually after a crash. I never worried too much about it - I stopped mountain biking a bit before carbon arrived as a frame material for MTBs.
As for road bikes - I would think the lack of triple chainrings would make it unlikely? (The chain just hangs there after it drops, rather than getting sucked in.)
