With the CYCLUS TOOLS snap.in EC 30 head tube reamer, diameter 30 mm, you can prepare head tubes with an inner diameter of 30 mm for installing a classic headset (with external cups). The new S.H.I.S. (Standardized Headset Identification System) allows you to easily identify the correct cutter, ensuring the right choice for every job. This system consists of the headset type and the associated head tube inner diameter (e.g., EC 34). EC (External Cup) indicates the classic headset, ZS (Zero Stack) the semi-integrated headset, and IS (Integrated Standard) the integrated headset.
