  • STANDARDISED FRAME AND FORK DIMENSIONS

    Head-Tube Bore-Top

    Head-Tube Bore-Bottom Stem Clamp Diameter Crown-Race Seat Diameter
    41,95-42,05mm 52,05-52,15mm 28,6-28,45mm 39,79-39,85mm

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

    • The four needed dimension are:
    1. Stem/clamp diameter of fork
    2. Crown-race seat diameter of fork
    3. Head-tube top inside diameter
    4. Head-tube bottom inside diameter

    Bearing position and cup type are identified as:

    1. EC (External Cup) Bearing contained within cups that are located outside of the frame
    2. ZS (Zero Stack) bearings contained within pressed-in cups where the cups and bearings rest inside the frame
    3. IS (Integrated) Bearings that fit directly into a bonded or machined interface that is integrated into the frame
    • The S.H.I.S. code is made of four alfanumeric series separated by / and |
    • The symbol | separates the upper form the lower headset parts
    • The symbol / separates the dimensions-type of the frame from the diameter of the fork steerer tube

    For example the code IS42/28,6 | IS52/40 of this headset is separated in four parts:

    1. IS42 identifies the upper headset as Integrated for a 42mm frame bore
    2. 28,6 identifies the diameter of the fork tube at the stem clamp of 28,6mm that is 1 1/8"
    3. IS52 identifies the lower headset as Integrated for a frame bore of 52mm
    4. 40 identifies the diameter of the fork tube at the crown of 40mm, that is 1,5"
