Chain damage on carbon frame, anything to worry about?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Chain damage on carbon frame, anything to worry about?

Is chain damage on carbon frame, anything to worry about? Or is it just cosmetic? Is there anything I should do to the frame to stop it from getting worse? The bike is a Glacier Black Ice and it's only a month old.

Bummer. If you trust your dealer, take it and show him for his opinion.

You can give the frame the tap test. Tap the frame towards the area, if it changes from a tap to a thud, the carbon frame is likely toast. If not it's probably OK a just cosmetic, I'd still have your shop check it out though. Good luck.

The pro bikes Cycling News features often have chain watchers. For example here on Tom Boonen's Specialized:



The chain stopper rests on the seat-tube and ensures the chain stays in place.

A special mechanism mounted by the mechanics keeps the chain in place and Ballan riding over the bergs.

Deda Dog Fang Roadbike Chain Guide is available aftermarket.


Deda's Dog-fang is a neat lil' widget that keeps the chain from falling off when moving from the big to small chainring.

for carbon frames they should be standard components, especially for compact cranks. my wifes cf lemond came stock with one, and it has these little aluminum plates glued in strategic spots on the stays and seattube .

The same thing has happened to me. Chain suck jammed the chain up in there but good. A friend has a Specialized bike (forget the model) with some sort of chainstay protector attached right behind the chainring. It looks like it may be metal. Anybody do an after-market one of these so that I can protect this spot from further abuse?

Don't let them get you down... that looks like a mere flesh wound.

Deda Dog Fang, Third Eye Chain Watcher, N-Gear Jump Stop.

My friend's Allez Elite came with what I'm pretty sure is a Dog Fang.

Not only that, if that chain comes off going up a hill you lose momentum in a hurry, and if you can't get your foot out in time . . . down you go . . . sustaining even more bike damage, not to mention ego damage.

I speak from experience, happened last week. I'm still pissed.

Even if it looks superficial, take it to get it checked out. I ruined my Lemond MJ carbon with a case of severe chain suck.

I'd get it checked out but it looks pretty superficial to me. That looks really similar to my frame, what is it?

Same thing on mine. Tore right through the cheap rubberized protector thingy, but I'm not too worried about it.
