SHIMANO11 Speed Chain Quick Link Connector SM-CN900 (2 Pairs)

I got this to replace the link that came with the new Ultegra chain I got directly from a Trek retailer. This link would always make a clicking sound at the jockey wheel which I tried to fix with more lubrication of the pin to no avail. The new link solved the issue - no more clicking noises.

They work great!

It does the job.

What I needed

Got a rocket science item, the links work as expected.

These are a tight fit and require some practice and the right tools.

I don't really know what to add.

Good to keep in my tool bag in case of a chain break. They go on quick, don’t add much weight and will get you back on the road.
