Time to weight something: 438,8 grams for the sized fork… wonderful. To complete this step just sand down the edges and your down with sizing. It is also necessary to wear a respirator because the fine dust of the carbon is more than unhealthy. Downside on this you lost your mark, so measure it more than once before cutting =)įor a straight edge a special saw blade is the best. To prevent the carbon to fray while cutting the best method is to wrap it with tape. On the allez the stack-formular looks like this: Headset Cap + Spacer (10mm) + Spacer (10mm) + Stem + Spacer (5mm) – 2,5mmīecause I forgot to take a picture before here is the final one of the whole stack… mea culpa. The final mark for cutting should be done with a knife. Make sure the cap of expander-plug is included in the calculation of the fork length. After that subtract half of the upper spacer so the ahead cap can take its space. To size the fork correctly it is useful to stack all parts together and mark the upper cut. Never use a star-nut inside a carbon fork, this will damage the fork! Use an expander! In the end the specialized expander look like this.

The extract of the expander is quite simple: unscrew the inner screw and “hammer it down”.

The expander holds the ahead cap which is responsible for the preload of the headset bearing pressure. Time to start… I already removed the expander inside the fork. Post as guidance? No warranty in ANY case of damage! Cane Creek Forty (ZS) IS42/28.6/H9 Carbon.
