HOW TO CUT A CARBON FORK STEER TUBE - See how I do straight and clean cuts.

- In this short video, I show how I cut carbon steer tubes.
I have developed that technique over the years. It is an advanced technique and you should have a base understanding of cutting and sanding before trying it.
Before attempting to cut your own fork, i strongly recommend practicing, and practicing again. Use steer tube left overs and use the right tools.
Steer tubes and forks are critical parts of your bike and failure to have good mechanical knowledge and experience before working on a bike could result in a crash, injuries and worse..s so please be safe, know your limits and bring your fork to a local bike shop if needed.

Thank you for this content. I cut my steer tube tonight, perfect. After I finished with the wet and dry sanding it was so immaculate, it's a shame it's hidden lol

That 's not how you are supposed to use the tool....it's better. Love the idea. Most people won't know why you are spraying the vice when you clean it. A pro doesn't want to breathe carbon dust, so he sprays the dust before removing it. A shop pro showed me once how to clean shop floors in dusty environments,,,,spray water , broom away, makes for crumbles instead of dust going all over. Pros have great tips! Merci Andreas. Respect your pros, even if you can do most things yourself, they do it day in and day out so for sure gain more knowledge than yourself however how many bikes you have! Always listen well when they are giving advice.
A pro would also use the saw guide that he already has there. Though admittedly the result is good enough
thanks for commenting. II will use some of your tips!
Andreas - You make great videos - I’m always happy when I see you have made a new one. Keep up the great work.
Thank you!
That slow mo on the cut!
Un art que j’apprécie de plus en plus.. bravo!
i think a lot of people are confused about leaving a spacer above the stem against conventional wisdom. This is the way I do it as well, because the expanding portion of the plug does not go all the way to the top, I prefer to measure in a way that the stem sits squarely where the expanding portion would be, and most of the time, it means having a small spacer above the stem.
Andreas, great video , and I will use this technique when I cut my fork. Two questions, if I may ask. 1. What size was the spacer before the cut to mark 2mm or 2.5mm? And 2. Does one have to take into account the @1mm that the expander sits above the steerer when fitted, to end up with 3mm for preload. I understand that this video is a bit older, and I understand I'd you are not responding to old questions. Again I find the information here very helpful. Cheers.
Hi Gary,
Thank you for the comment :)
I do not remember the width of the spacer, but I would think it is a 2.5
I always take in account that height of the expander, and every fork, stem, expander combination require a different measure.
I rarely cut steerers without leaving enough material for a spacer on top of the stem for longevity and reliability reasons.
If you are using a enve integrated stem or similar product, then you would have to make sure there is no more than 3mm of space between the steerer and the stem top part so that requires a bit more of measuring.
I also always make sure that the outside diameter of the expander is smaller than the steerer so that the stem does not clamp on the expander, which would affect safety.
Thanks for watching!
very clean and thanks. Is there a reason why you didnt use a saw guide tool to get the cut straight?
The guide is about 2-3mm wider than the saw blade, so there is room for you to be a little crooked. The spinning of the fork ensures a perfectly straight line, genius and simple solution.
great video
I really like your technique. Just want to make sure I am seeing this right, are you using a shorter (~2.5mm) spacer when you measure before cutting so that you have the right room leftover for compression with a 5mm above the stem?
Hi! Thanks for watching. In this case yes.
I measure many times before cutting after confirming the customers fit.
Have a great day!

hi I have a carbon fork that I just bought and I have to cut it, I don't have the tools to do it properly nor the ones you are alternatively using and I'm scared to mess it up if I just go for it with a saw while clamping it on a normal vice: would you recommend to take it to a shop?
@@Daniele_-ub4zh please bring it to a shop. Much easier, and not really expensive . Thanks for watching
@@AndreasIhm thanks man
500!!! Woohoo! 👏
Question : Why didn't you use the saw guide? Pls don't get me wrong it's just for knowing it.
Guides have enough gap that a cut can move a bit. Also, practicing a cut without a guide is essential for cuts you have to perform on the bike (fully integrated aero cockpits is a good example) and odly shaped steerer as well (like cervelo, look, cannondale)
Thanks for watching
There, where I find it difficult to understand: it is that you do not take into account the expander in the measurement because it adds a small height. In this case, did you then place a higher spacer (than the one initially placed when taking the measurement) above the stem so as to have 3mm more for compression?
I did it in account. I used a smaller spacer to make the mark knowing exactly which spacer I would use on top of the stem. Thanks for watching!
spacer slight of hand..not for 1st timers..🤣
great video, i just cut a fork not knoweing it was carbon with a pipe cutter. it didnt go well, i got the first layer then i needed to use a saw. What is the name of thing you put in youir vice to be able to have the stick it into the pipe vertically called?
Hi, it is called a cutting guide. Most bike specific tool companies will make one. This one is from Park Tools.
genius
What's the advantage of rotating the fork while cutting?
its easy to cut an angle if you dont rotate the fork. dont believe me try it for yourself: go get some old pipe and cut and see
There are two advantages:
1- the cut is straight because the cut also becomes the guide.
2- there is not carbon splinter on the exterior surface of the fork. This makes it clean and safe if ever someone has to remove the stem for any reason.
Thanks for watching and sorry for the delay before answering!
Man you've lost 30 min of your life fot thing that takes 5 mins.
Nothing wrong with putting some extra love and care into a job like this.
30 mins? That's fast dude! Measuring, remeasuring, sanding, cleaning, damn!
