Frequently asked questions

Which chain does this sprocket fit?

ASA 80-1 (16A-1) roller chain with a pitch of 25.4 mm. A simplex sprocket requires a single-strand (simplex) chain.

Does it fit 16B chain?

No. 16B chain (European standard) has the same pitch and roller diameter, but a different inner width (17.02 mm instead of 15.88 mm). The ASA 80 sprocket is designed for American-standard chain, so the two systems should not be mixed.

How should sprockets be aligned during installation?

The driving and driven sprockets must lie in one plane. Alignment can be checked with a long steel straightedge placed against the sides of both wheels or with a laser alignment tool. Even a small misalignment wears the sides of the teeth and speeds up chain wear.

When does a sprocket need replacing?

It should be replaced when the teeth start to look like pointed shark fins or are clearly bent to one side. Running on such a profile quickly destroys even a new chain, so a worn sprocket must be replaced.

Can a new chain be fitted on a worn sprocket?

This should not be done. A worn sprocket has a changed tooth profile, so a new chain runs unevenly and elongates quickly. The rule is: new chain - new sprockets.

What does the lead time depend on?

When ordering, please check the current stock level of this sprocket - the lead time depends on it and is clearly stated according to the quantity available in each warehouse. The stock level is shown above the product price and may vary depending on the warehouse.
