Important information
Zero Stack (ZS) head tubes do not need any tapered bushings. Using tapered
bushings during an ZS headset installation can irremediably damage the cups.
Using the headset press without the tapered bushings is here warmly
recommended.
It is also possible to use the headset press without any tapered bushings during
some 1’’1/2 headset cups installation.
Important information
Using the tapered bushings during external headset (EC) cups with pre-installed
bearings installation is not recommended : the pressure transmission is done by the
bearing, that could damage it.
Using the headset press without the tapered bushings is here warmly
recommended.
