Very good! I'll be keeping these as teaching-aids, if you don't mind. You're chain can definitely stand to lose a link. Find the master-link (or whatever the brand-name) and take the chain apart. Remove a link with a chain-tool. No got or understand? Ask your bike-shop to remove one link. Ask to watch. And buy a chain-tool so you can put it back together at home. Or wheel the whole beast to the shop and ask them to do this.

You might even need to take off 2 links, but I doubt it. But taking apart (breaking) chains is a simple skill that all bike owners should know - and have the right tool to accomplish.

Let us know, please, how it goes.
