Review on Origin8 Pro Threaded Headset - 1 Inch Steerer by Erik Snyder

Fits the old JIS standard. High quality bearings, nice finish. The reviewer who stated that the JIS frame shell diameter is 30.2 is confused. JIS Frame Cup is indeed 30.0. The difference between JIS and ISO is the fork crown (JIS=27.0 and ISO=26.4). 30.2 frame shells are found on older Professional Campagnolo, Raleigh and some older French and Italian motorcycles. Older French and Italian bikes were the only ones available with 27.0 fork crown and 30.2 frame cup. As for the height, yes, it's very tall for a 1-inch headset. Its height is 42.5 mm. Finding the right size for a 1 inch headset can be difficult. If you don't know how to do this, have a good bike shop do it for you. This is a link to all the information you might need about the headset. [.]
