Finally, after riding Campagnolo for 13 years (started out with Shimano) I have at last bought their “proper” chain tool :-)
It is a thing of beauty, cleverly designed, well made & lovely to use!
Why didn’t I buy it earlier? ......... well, the price has a lot to do with it :-/
I suppose any chain tool can break a chain, but it’s the joining process that’s getting more & more delicate as chains gets narrower due to cassette sprocket numbers increases ........ now that 12speed is available & there’s even talk of 13 speed soon too ...........
I don’t use “speed-links” or “quick-links” to join my chains, I always use the rivet supplied with the chain. Although I do carry some in my tool bottle in case of emergency out on the road.
This tool is especially designed for Campag 11speed chains (but good for other speeds too) as it does the “peening” with absolute ease :-)
I find it that it’s actually a pleasure to change chains now when using this tool :-)
