Chain knocking

[Johan Bornman]

Hey Johan, thanks for the advice. What would cause them to have worn so badly? I figure it's a symptom of something else. The top pulley seems less worn.

Rode on Saturday and the knocking didn't seem too bad but haven't checked properly. Will visit my LBS for new pulleys

, but they don't have stock ATM. PS any idea how much pulleys should cost?

 

Also, curious why you have a specific ladies course and why is it only one day?

 

That's how pulleys wear. Bottom one takes all the chain tension and the dirt reaches there first. Nothing strange about that.

 

Pulleys are consumables. The reason yours are worn is that you ride too much. Shimano pulleys are cheap. Just replace them.
