Do you like choices The Wolf Tooth Components Drop Stop Chainring gives you lots of them. You can run the Drop Stop as a single ring without any kind of chain keeper. Or even a triple if you're feeling old school. The Drop Stop also gives you sizing options. It comes in even-numbered teeth from 30 all the way up to 38 and two BCDs. There are even four color choices--black, red, blue, and gold--so you can match it to your current setup or set it apart to emphasize the bling.
