Please choose the correct ending to complete the given sentence: Cars & Other Vehicles: [header] How to fix a tangled bike chain [title] Slide the chain onto the smallest sprockets. [step] Sprockets are the metal plates with teeth that move the chain. Since you won't be able to ride the bike, you'll have to move the sprockets manually.

[substeps] If you're inexperienced, use sprockets that are thicker than your chain. Ending2: To do this, simply lift the chain and move it to the smallest sprocket. Do this on both the rear and front chain sets. Ending3: To replace the sprockets and snap the sprockets, slide the chain onto the slightest sprockets. [substeps] A chain of sprockets is an attachment to the parts of the sprockets that the bike has caught. Ending4: To start, slide the sprockets onto the larger sprockets. When you place them on, they have to be closer to you; if you move the sprockets near the sprockets it will become jarring.
