CYCLUS TOOLS head tube reamer Set - EC34, IS42.
With this head tube cutter set from Cyclus Tools, you can prepare head tubes with different inner diameters and milling depths for headset assembly with classic external bearing cup headsets. The cutter ensures exactly flat and coaxial head tube seats are created.
When naming the individual cutters, care was taken to use the new naming system (S.H.I.S. - Standardised Headset Identification System). It consists of the type of headset and the corresponding inner diameter of the head tube (e.g. EC 34). EC (External Cup) stands for the classic headset and IS (Integrated Standard) for the integrated headset.
