Broken Teeth CS

8 posts in this topic

I broke two teeth on my countershaft sprocket today. I'm just wondering what typically causes this to happen or was it just a faulty part? The chain and sprockets where replaced at the same time probably three months ago.

Could have got a small tough stone/pebble dragged into the teeth

I thought about that, but it was two teeth with three teeth between them.

How much riding time(hours) do the chain and sprockets have on them and what have the conditions been like? In what shape are the rear sprocket and the chain (if you can, remove the chain and roll through it to see if there is any binding) itself?

If they are pretty much fine, I have to say that kind of damage sounds pretty weird. Steel(I suppose the Ironman is one of these) typically wear out later than front sprockets, aluminium rear sprockets faster). Mud wears out chains and sprockets like all get out (really, about 5 times as fast).

I've never had this pattern of breakage. I usually see broken teeth next to each other. As it was an upmarket chain its less likely the chain could have locked-up like an inferior one might have. Maybe the sprocket had a defect.
