What size do I need

You need to ensure you have the right size Chaintamer for your bike because there are plenty of different frame and drive-train combinations.

Here is a demonstration video showing how to measure up:

  • Place the chain in the largest cassette gear and chain ring.
  • Measure the distance from the top of the chain stay to the top of the chain, approximately halfway along your chain stay -as in the picture below.
  • Round up to the nearest cm.
  • In the example below the chain almost reaches 7cm, this will need a size 70 Chaintamer.

  • That’s all, you’re done! Buy Now
