Here's one for all the tech heads out there:


Hamilton, Bermuda – November 9, 2010 – To address the changing landscape of bicycle headsets, a group of leading headset manufacturers have collaborated to develop a standardized “language” for headset fitment. The new Standardized Headset Identification System (S.H.I.S.) creates a common language for describing modern bicycle headsets. The system provides comprehensive and scalable headset fitment information in a standard format; making it easier to communicate headset requirements based on frame and fork interfaces.

“As a bicycle manufacturer I have participated in many conversations with customers who are struggling to understand modern headset fitment,” says Michael Bonney of Orange Mountain Bikes. “During Eurobike and Interbike I suggested to a couple of headset makers that a universal system for talking about headsets was needed, and I’m excited to see it happening.”

The Standardized Headset Identification System (S.H.I.S.) incorporates the four critical interface dimensions required to fit a fork to a frame, as well as explicitly noting bearing location/cup type.

The group of companies leading the development of the new headset naming system include: Acros, Cane Creek, Hope, Race Face, Reset and Ritchey. Each of the participants has committed to integrate the Standardized Headset Identification System into their respective businesses over the course of the next year and encourage additional headset manufacturers to follow. Select bicycle parts distributors (including US distributor BTI [www.bti-usa.com]) will have partial integration of the S.H.I.S. in their 2011 catalogs with further inclusion throughout the year. On the bicycle manufacturing level, several early adopters will begin using the system on their new model-year bikes.

S.H.I.S. creates a common language for describing modern bicycle headsets. The system provides comprehensive and scalable headset fitment information in a standardized format; making it easy to communicate headset requirements based on frame and fork interfaces.

The system addresses the critical interface dimensions required to fit a fork to a frame, as well as bearing location/cup type. To determine fit, four dimensions are needed: (1) stem-clamp diameter, (2) crown-race seat diameter, (3) top head-tube inside diameter, and (4) bottom head-tube inside diameter. Bearing location and cup-type are identified as (a) external cup (EC), (b) semi-integrated or ZeroStack (ZS), or (c) integrated (IS).
