Information


Our headset crown races are designed with a “split” to allow for tool-free installation and removal.  We also offer 2 adapter races to allow you to run a 1-⅛” (30mm) or 1-¼” (33mm) fork on headsets that use certain lower cups (EC44, ZS56, IS52). On these headsets you can order any of the 3 crown races to be included in the complete headset and order the adapter race you need as a separate item. 

 

Specs

  • HSRACE4033 adapts EC44, ZS56 or IS52 lower cups to a 1-¼” (33mm) fork crown
