Cut a fork steerer tube with the fork in the frame How-to Tutorial

[@bradlandry2426]

Thanks for this tutorial. I followed it step by step and it worked like a charm.

[@ridesofjapan]

Glad it helped!

[@RixterNow]

Looks sharp. Since you’re so particular, it’s recommend you put a layer of nail polish over the cut carbon to prevent water and sweat ingress

[@ridesofjapan]

That's an excellent suggestion! Never heard that tip before... Cheers!

[@RixterNow]

Rides of Japan this guy Rahoul is a former Boeing aircraft engineer and knows more about carbon than anybody. This is his video about sealing a carbon cut kzbin.info/www/bejne/n5bIdKSiht5oqbs

[@gfm8421]

Exactly what I needed! Thanks!

[@81caasi]

very helpful, I'm doing the exact same thing now :) Top it up with some relaxing jazz music... no stress!

[@zodgzod]

Thanks. This is just the video I was looking for. Now to order the guide and hacksaw!

[@dreadknot2238]

wow look like your preparing your bike to have a dinner at a restraunt

[@Macm73]

Nice one, was thinking about doing this to one of my bikes. Definitely will after seeing this. 👍

[@richfi9576]

is that steerer tube long enough? Seems like the top stem bolt is above the level of the tube which would mean force from the bolts is not evenly applied to the tube, potentially breaking the end of it. I would think you don't need that small spacer. Then again, I haven't cut a steerer tube. ETA: another great watchable bike video with enjoyable music!

Hello sir! Very good and excellent how-to YT Videos! Wishing you all the very Best always! /Best Regards, Charl (Sweden)

[@ridesofjapan]

Tackar så mycket! 🇸🇪

[@MrGarnet108]

I want to do the same but is thinking how to prevent the fork from slipping down the headset, now I know what to do, thanks!

[@vlahovicsamira7084]

Nice job, I Saw a vidéo with an Italia mechanic building bikes and he did liké you. Unfortunately I Saw it too late, and I put the frame with the fork on a table to have it horizontally...

[@abdulqodoosalsowail4486]

Your left hand position while cutting it wasn't easy to watch

[@Roostsandboost]

yes cut away from body parts

[@YesItsKevin]

@@Roostsandboost i misread that and thought it said "yes cut away body parts"

[@user-uh6lm5wv6n]

What expander plug and top cap did you install at the end? I really like the low stack and would like to buy one.

[@johnbananastackerton1138]

Big thanks for all your videos. Why not use a pipe cutter instead of the saw?

[@ridesofjapan]

On metal steerer tube its fine but, doesn’t work good on carbon

[@mrskeltal3281]

Last time I unscrewed the headset cap bolt it unscrewed the other bolt for the expander along with it, so the plug all fell to bits and went into the frame! why!? It took a while to fish it out as the hose for the front brake runs internally down the steerer...

[@seanpaul3050]

Remember the old design. You adjusted the stem up and down in a few seconds. If something isn't broke, dont fix it.

[@cheachyang3502]

hi where to buy the clamp support ?? thks boss , what the tool name ??

[@bengt_axle]

Don't you need to reposition the expansion plug after cutting the steerer?

[@ridesofjapan]

Most likely yes, it should be removed when cutting any way. Get the compression plug positioned bang in the middle of the stem clamp if possible.

[@tagzedawg]

Hi! What's the music over the very end of the video?

[@timperry8961]

So just keeping the front wheel in will work, to keep the fork in place?

[@ridesofjapan]

Fork will stay in place by the saw guide as long as you keep the bike in the ground or in a race-style bike stand (that attaches to the dropouts/axles of the bike)

[@pss999]

Do you not have inline quick connects on the hoses so you can remove the fork?

[@ridesofjapan]

+Paul Schwartz no, they only come with complete builds from what I understand.

[@antoniosanto2617]

Hi quick question, I should do the same job on my bike but only for 1cm, when I mark the part to remove I should mark 1cm (in my case) right? Exactly the same measure that I will remove…

[@ridesofjapan]

If you want to remove a 1cm spacer then cutting 1cm of the steerer tube should do the trick :)

[@antoniosanto2617]

@@ridesofjapan the reason why of my question depends on what I read on some website: add 2/3mm to the measure that you want to remove 🤔. In my case I’d like to remove just 1cm as said

[@ridesofjapan]

That’s usually the rule when you first cut a previously uncut fork

[@antoniosanto2617]

@@ridesofjapan ok mate, for me it’s the first time that I’m cutting the fork and of course my fork is uncut fork, so if I understood correctly I should cut just 1cm, nothing more, right?

[@ridesofjapan]

When you said you only want to cut 1cm it sounded like you are already riding it. An uncut fork usually have a lot more steerer that has to be cut than 1cm. Make a mark above the spacer on top of the stem, then make the actual cut mark ~3mm lower. The end of you steerer need to be a lower then the top of your stem/spacers to for proper head set preload.

[@TownofJezza]

DONT! that's how you crush a carbon steerer - the top Bolt is above the expansion plug and the stem isn't mounting the whole surface of the steerer

[@cygnusx1858]

What does that expander thingyy do?

[@ridesofjapan]

Main function is to help preload the headset(together with the top cap). It also acts to support the camping force of the stem as people tend to over tighten it.

[@TownofJezza]

the way he installed it - not much

[@nitrouspeed3583]

I don’t have a hacksaw but my university has a plasma cutter I can use, will that work on carbon?

[@Stoffendous]

Use a laser!

[@heksogen4788]

Is there any tangible benefit of doing this beside look factor?

[@ridesofjapan]

Depending on your expander, it might be necessary to get the expander in the correct place I relation to you stem clamp.

[@heksogen4788]

@@ridesofjapan I was talking about cutting the steer tube. Why would someone do that, beside look factor?

[@zap...]

That was weird.

[@BryanPike]

UM, no... do not use this as a guide.
