Which headset bearing do I need?

Headset bearings are a mine-field.  Our research has pulled up well over 40 different sizes and types, some common and some bike specific (looking at you Trek and Cannondale!). Here at Shockcraft we stock 9 of the most popular sizes and several of those sizes in a few different flavours.

To make headset identification as easy as possible we've created a Headset Bearing Identification Chart which you can download and print as a PDF.  We've even made measuring headset bearings simpler.  So grab your verniers and a credit card or business card (yes seriously) and hit the link above.

If it still doesn't make any sense, give us a call or email.
