CYCLUS TOOLS snap.in ZS 56 – Head tube reamer SN.31-S

With the internal cutter, it is possible to prepare head tubes with an internal diameter of 56 mm for mounting integrated headset series. The new S.H.I.S. (Standardized Headset Identification System) allows you to identify the correct cutter, ensuring the right choice for every application. This system consists of the headset type and the corresponding internal diameter of the head tube (example: EC 34). EC (External Cup) indicates the classic headset series, ZS (Zero Stack) the semi-integrated headset series, while IS (Integrated Standard) indicates the integrated one.
