Alternative Shifters

Most road bikes today come with integrated brake and shifting levers, or brifters. They are more comfortable and usable than traditional styles. Let's look at some available options.

Shifting mechanisms

Shifters work by increasing or decreasing the tension on the shift cables to move the derailleur into place.

Indexed

Indexed shifters click into place and move the derailleur one gear. They allow for precise shifting, but need to be tuned and parts are made for specific speeds and derailleurs. Brifters are all index shifters.
