Sprocket Wear

[Guest]

There's no substitute for actual measurement and experience. While in Chicago, we were looking at a sprocket that had some minor wear. I could barely see anything at all, but a couple of guys commented that it was enough that they'd consider changing.

Take a look at this sprocket. I know this is old and needs changing, but for the life of me I can't see how I'd identify it if I couldn't personally vouch for 2300 miles of riding on it before I even got a hold of it.

Can you show me where the wear I should be seeing is?

It is wallowed out between the teeth.
Put a roller in there and you will see ALL of the clearance that shouldn't be there.

So you mean that it's worn away in the "valley" essentially? And if it were new the roller would fit completely snug in there?

Pretty close.
The chain has been loose more than it has been adjusted/lubed.
If you keep up with the adjustments, it lasts a lot longer.
Also the brand/quality of the chain makes a huge difference.
