Standardized Headset Identification System (S.H.I.S.):


The 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 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 of fork, (2) crown-race seat diameter of fork, (3) head-tube top inside diameter, and (4) head-tube bottom inside diameter. Bearing location and cup-type are identified as (a) external cup (EC), (b) semi-integrated or zero stack (ZS), or (c) integrated (IS).

Nomenclature:


EC: Bearings contained within cups that are located outside of the frame (external cup).
ZS: Bearings contained within pressed-in cups where the cup and bearings rest inside the frame (zero stack).
IS: Bearings that fit directly into a bonded or machined interface that is integrated into the frame (integrated).

1a Verarbeitung des Produkts und einwandfreie Montage und einstellung war gewährleistet. Die schlechte Bewertung wegen einer viel zu fest angezogenen Schraube kann ich nicht verstehen. Wie sagt man so schön: "Don´t be a fool and use a Torque-Tool"!
Nebenbei sei auch erwähnt dass der Zentrierring zwar aus Plastik ist, Acros aber mitgedacht hat einen Zweiten als Ersatz mit ins Päckchen zu packen.
