Here we have available all the common types of Fox shock bushings. In order to determine which bush size you require there are a few options. Some bicycle manufacturers provide this information in their owners manuals or make the information available on their respective websites. Failing that the most accurate way is to measure them, preferably with a pair of digital vernier calipers. These are a useful tool which can be purchased online from places like Amazon or Ebay for approximately £5 - £10. As you can see from all the available sizes of the low friction bushes below (drop down list) a ruler is not always accurate enough! As always, if in doubt, please contact us before placing your order!
