ZTTO 4444T HEADSET// HOW TO INSTALL FORK WITH TAPERED STEERER TUBE TO OLD FRAME WITH 44mm HEADTUBE

[@bbggh4386]

Very useful and straight forward really good English as well, well done my friend and thank you , very helpful

[@COOLBIKEyt]

Thanks a lot, I'm glad I could help.

[@markjmaxwell9819]

For people that have a straight headset tube this will make your headset as good as a tapered headset tube. Depending on the ID and angle of the bearings used a straight or tapered fork can be used....👍

[@COOLBIKEyt]

More or less… yes :)

[@chemim888]

This is the right solution for straight tube to tapered. Thanks for the info. Can you give a link where I can buy the headset? Thank you.❤

[@COOLBIKEyt]

You can find it on Aliexpress, as: ztto 4444t headset :)

[@SafwanRahmanofficial]

How about the height of the bottom cap? I have a short steerer tube, and afraid that it might be too short

[@COOLBIKEyt]

It height is 13mm, and I think it's one off the smallest

[@TechRender98]

@Safwan Rahman saya pun pakai marin bobcat juga. nk convert ke tapered. Abg beli size yg mana ya?

[@sekorak]

Can we reuse the old top bearing cup? Or need to install the new one also?

[@COOLBIKEyt]

You can leave it, only the lower cup need to be replaced.

@@COOLBIKEyt nice. Thank you..

Hey, great video, but i have a question, does the cane creek 40 series with the zs44/ec44 does also work on straight headtubes?

[@COOLBIKEyt]

Hi, yes. These headsets are equivalent to ZTTO ones from the movie. If you have internal headtube diameter of 44mm, and enough space for the lower cup flange, they will fit.

[@jesusserrano546]

So, what do I have to do in order to buy the right headset? Take the measurements from the upper and lower parts? Then what? Thanks.

[@COOLBIKEyt]

Check if the inner diameter of the headtube on the top and bottom is 44mm. If so, will a 10mm high flange of bearing cup will fit from the bottom. And finally, if everything is correct order headset. Good luck:)

[@jesusserrano546]

​@@COOLBIKEyt I just saw a video of a guy doing the same change, and he's doing it to a Trek Marlin 7. I was surfing on the internet about the differences between the trek marlin 7 and Marlin 5 (the one I have), and the frame and headset are the same for both models (actually, for all the Marlin series), so, I think I can buy the headset he used, which by the way, its the same headset you reviewed. What do you think? Pd: Here is the video kzbin.info/www/bejne/larben-Cp5Zlr6s

[@garrinchatuga]

Where did you buy ?

[@COOLBIKEyt]

Hi, on Aliexpre...

[@kennangargarita7179]

So this ztto headset can be used to a 34mm headtube to convert into 44-44t for tapered forks? Just some clarifications on my guessing.

[@COOLBIKEyt]

No, because flanges in ZTTO have a diameter of 44mm, so I will not go into the narrower headtube 34mm. In 0:46 you have a graphic showing how it works.

[@kennangargarita7179]

@@COOLBIKEyt thanks, i do have a 26er fullsus frame, its not integrated 44mm, it was 34mm, maybe i cant use a tapered fork for that extra frame i have.

[@COOLBIKEyt]

@@kennangargarita7179 Yes, you'll probably have to use that fork to another frame. This headtube is too narrow.

[@Sayan_here]

Does the top dust cap has rubber sealing?

[@COOLBIKEyt]

Hi, upper cover have a plastic seal on the end, there is no oring inside or anything else.

[@FATFORKS]

I wonder if the shorter insertion depth could cause the headtube to fail?

[@COOLBIKEyt]

Which "shorter insertion depth" do you mean?

[@FATFORKS]

@@COOLBIKEyt I mean with the ZTTO cup the insertable section is only 8.5mm deep, whereas with the Cane Creek which I believe is the original adpater cup the insertion is 15mm and they recommend getting the headtube reamed to accommodate if necessary. I assume they designed it this way to provide more surface area to distribute the forces and prevent ovalization of the headtube. That 8.5mm insertion depth with the ZTTO is a little troubling because a semi-integrated headtube is not designed to have lateral forces of leverage outside of the tube itself such as would be the case with this adapter cup.

[@COOLBIKEyt]

@@FATFORKS It seems to me, that such a short cup collar is a must. Because I had a case where the headtube of one frame was so narrow inside, that it was impossible to press the cup to the end. I have already installed a few sets of these headsets, and there are no problems with them, but this was on bikes for normal riding, not for enduro/trail/dirt purpose.

[@obxarms7685]

@@COOLBIKEyt What was the headset that was too long??

[@COOLBIKEyt]

@@obxarms7685 If I remember correctly, it was NECO.

[@obxarms7685]

So the FSA headset flange is too tall??

[@COOLBIKEyt]

It depends on your frame. You need to measure how much space you have in your headtube,

[@wvttzz.]

Will this fit a tapered fork to a straight tube frame

[@COOLBIKEyt]

Yes, if the head tube is 44mm.

[@sc_273]

I have a problem! My frame headtube is 50mm, i want to make it taper, how do i do it? What dimensions of cups and bearings i need?

[@COOLBIKEyt]

First you need to know the exact inside size of the headtube. 50mm is a strange dimension...

[@sc_273]

@@COOLBIKEyt its a DH Specialized status 2 2014, its got 50mm the whole headtube from top to the bottom, right now its set to 1.1/8”, i took bottom out and now i need new bottom cup for taper fork (39.8/28.6mm)

[@COOLBIKEyt]

@@sc_273 From the Status specs in Specialized webside, you already have tapered there: 'HEADSET Semi-integrated alloy cups for 1-1/2" headtube and 1-1/8" steerer, cartridge bearings"

[@COOLBIKEyt]

Probably if the headtube is 50mm on the outside, the walls are 2x3mm, so it's 44mm on the inside. In this case, these headsets will be ok, but I advise you to measure and make sure.

[@sc_273]

@@COOLBIKEyt Actually, they are 50mm from the inside, and because od the DH frame, walls are 5mm each, si 60mm outside. In 28.6/44-50.6/39.8, what diameter of bearing is on the buttom?

I think your headsets are FSA No.10 ( ZS44/28,6 | ZS44/28,6 ), so this ZTTO should fit.

@@COOLBIKEyt yes....that is for the upper diameter....what about lower.....is ec 44/40 correct diameter for lower

[@COOLBIKEyt]

@@shivamhazarika9541 Lower should be the same as upper. You can just take the frame i measure it.

@@shivamhazarika9541 From what I can see on Marin website, headtube in Bobat Trail 4 2023 is straight, and the cups are the same on top and bottom. But if you say otherwise, then I don't understand what is the problem. Just take a measure tape and measure it.
