What can you do to extend the steerer tube?
Today I'm going to extend the steerer tube by 35 mm
Let's begin by taking out the stem and star nut
So here I have a threadless converter and a headset expander
The expander is an alternative of star nut
It's simple to install and remove
The converter is 22.2 mm and it fits with 1 1/8" forks
The original bolt is too long so I'm going to use a 4" screw and a hex nut
You'll also need a M10 flange nut
Put the flange nut into the converter
Insert the screw and wedge
Take the hex nut and tighten it slightly with the screw
Now the converter is ready, put it into the stereo tube
Tighten the hex nut with a ratchet
Check and put it to the desired position
The converter is too long
Put it back into the steering tube
Bring out the expander and install it into the steerer tube
Put back the spacers and other components
The steerer tube is now extended to the desired length
