This pocket emergency tool is exceptionally handy: It’s one of the smallest of its kind in the world, and since it is ultra-light - only 80 gm – it’s a smart addition to your tool bag. The chain tool is compatible with all derailleur chains, and it includes a spare Connex link.

Operation couldn’t be easier: If the chain breaks, simply remove the defective link from the chain and re-connect it with the Connex link.

How it functions is demonstrated in the detailed Operating Instructions in the download area.
