Description

The KMC K1 is a narrow single speed chain supplied at 112 links, which is enough to size down to a BMX drivetrain and still have links spare. It comes in a silver finish.

A KMC connect link is included, so once you have cut the chain to length you can join it back up and get on with the build.

Features

  • Single speed, narrow width. Built as a narrow single speed chain, so it runs on a standard BMX sprocket and driver.
  • Connect link included. A KMC connect link comes with the chain, so you can join it back up after sizing.
