Cyclus snap.in head tube reamer

With the internal milling cutter you can prepare head tubes with an internal diameter of 30 mm for the head set assembly of the classic head set (with external bearing shells).
When naming the individual cutters, care has been taken to ensure that the new naming system (S.H.I.S. - Standardized Headset Identification System) is used. It consists of the type of headset and the corresponding internal diameter of the head tube (e.g. EC 34). EC (External Cup) stands for the classic headset, ZS (Zero Stack) for the half integrated headset and IS (Integrated Standard) for the integrated headset.
