Choosing idlers and chain tools
For an idler sprocket, match the pitch of your chain, then choose the tooth count and bore to suit your idler arm or mounting. The listed pitch is in each product title. Idlers are listed as single pitch or double pitch, so check which type of chain you are running. For tools, choose the size that covers your chain number: the No. 1 breaker and puller suit smaller chain and the No. 2 the larger sizes in the ranges above.
Finer idler sprockets for tensioner arms (SE15 to SE45) are listed under chain and sprockets.
Always check the data sheet. Confirm pitch, bore and suitability for your drive before ordering.

Chain idler and chain tool FAQs
What does an idler sprocket do?
An idler sprocket runs against the chain to guide it and take up slack, without transmitting drive. Choose one with the same pitch as your chain.
What is the difference between single pitch and double pitch idlers?
They suit different chain: single pitch idlers are listed for standard pitch chain, and double pitch idlers for double pitch chain. Check the pitch in the product title against your chain.
What does a chain breaker do?
A chain breaker pushes out a pin so you can shorten or open a roller chain. The No. 1 suits ASA 25 to 60 and BS 06B to 12B, and the No. 2 suits ASA 60 to 100 and BS 12B to 20B.
What is a chain puller used for?
A chain puller draws the two ends of a chain together so a connecting link can be fitted. The No. 1 covers 25 to 60 pitch chain and the No. 2 covers 60 to 100.
Where are the tensioner arm idler sprockets?
Finer idler sprockets for SE15, SE18, SE27, SE38 and SE45 tensioner arms are listed under chain and sprockets.
