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....👍
If you already have 1.5'' at the bottom, then you have tapered spacing already, why change it ?. If your upper cup is also 1.5", there are cups with reduction to 1 1/8", but you have to look for them.
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.
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:)
@@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 ruclips.net/video/_yxILLr12yI/видео.html
@@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.
@@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.
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.
@@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 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)
@@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"
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.
@@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?
@@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.
Very useful and straight forward really good English as well, well done my friend and thank you , very helpful
Thanks a lot, I'm glad I could help.

More or less… yes :)
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.❤
You can find it on Aliexpress, as: ztto 4444t headset :)
Is there a version of that for a 1 and 1/2 inch straight tube for a straight tube frame?
If you already have 1.5'' at the bottom, then you have tapered spacing already, why change it ?.
If your upper cup is also 1.5", there are cups with reduction to 1 1/8", but you have to look for them.
How about the height of the bottom cap? I have a short steerer tube, and afraid that it might be too short
It height is 13mm, and I think it's one off the smallest
@Safwan Rahman saya pun pakai marin bobcat juga. nk convert ke tapered. Abg beli size yg mana ya?
Can we reuse the old top bearing cup? Or need to install the new one also?
You can leave it, only the lower cup need to be replaced.
@@COOLBIKEyt nice. Thank you..
@@sekorak You welcome
Hey, great video, but i have a question, does the cane creek 40 series with the zs44/ec44 does also work on straight headtubes?
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.
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.

Does the top dust cap has rubber sealing?
Hi, upper cover have a plastic seal on the end, there is no oring inside or anything else.
I wonder if the shorter insertion depth could cause the headtube to fail?
Which "shorter insertion depth" do you mean?

@@COOLBIKEyt What was the headset that was too long??
@@obxarms7685 If I remember correctly, it was NECO.
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.
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
Yes, you'll probably have to use that fork to another frame. This headtube is too narrow.
So the FSA headset flange is too tall??
It depends on your frame. You need to measure how much space you have in your headtube,
Will this fit a tapered fork to a straight tube frame
Yes, if the head tube is 44mm.
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?
First you need to know the exact inside size of the headtube. 50mm is a strange dimension...
@@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)

Where did you buy ?
Hi, on Aliexpre...
sabras? el modelo pero de la marca FSA
FSA ORBIT ITA
Thank you
You welcome :)
Hii...can you send the link for the purchase
Yt is blocking links. Search it on aliexpress and that's it.
My bike is Marin bobcat trail 4
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
@@shivamhazarika9541 Lower should be the same as upper. You can just take the frame i measure it.
@@COOLBIKEyt lower different bro... either it should be zs56/40 or ec44/40
