Hey all I need your help

Below is a picture of what I was told was an adapter for frames with 1"steerer tube to work in conjunction with 1 1/8 headset. If this is the case can somebody please explain how I would use the certain parts? Is it strong and safe? The silver rings are only plastic.

I guess I need detailed instructions on how to set this thing up. I am starting to build my new frame.

Actually while putting these pieces back in the bag the two silver rings clanged together and they are definetely not plastic. They are metal.

Can someone explain why you would want to use a headset adaptor?
If you have a 1" steerer, use a 1" headset

TotalKos

I have an extra headset already and it happens to be 1 1/8". Is it not appropriate to use the adapter?

Forget the photo. What exactly are you trying to do? Are you trying to install a 1 1/8" headset on a frame with a 1" HEADTUBE???? Or are you trying to install a fork with a 1" steerer tube on a frame with a 1 1/8" headset??? When you say frames with 1" steerer tube, you mean a 1" headtube???? Steerer tubes refer to forks only. Please rephrase your question.

TotalKos

OK, I have a 1" headtube, I have a 1 1/8" headset. I have what was explained to me as an adapter for the conversion but I thought {How could a bigger pipe fit into a smaller one?} I think the headtube is not 1". Is there something bigger than 1 1/8" headtube. You know what I am writing this in the middle of getting power back so I am all over the place and we are probably going to lose power here for the next little while so I will deal with this later. Sorry, thanks for the attempted help. Feel free to respond, I'll get it eventually. Thanks.

By the way.... YAY THE POWER IS BACK ON!!

Cannondale and a couple of other manufacturers used to have 1 1/4" headtubes for their Mtb frames several years back. Simply by looking, there's a huge difference in headtube diameters between the two. What frame do you have? Anyway, personally, I've never seen anything like what you're trying to describe or trying to achieve. If you have a 1" headtube, it's so much easier to just get an inexpensive 1" headset.

TotalKos

It's a Giant ATX 890. It's definetely bigger than my Kona Nunu. It probably is 1 1/4", would I still be able to get a headset for it?

i think the giant atx uses the 1 1/8 headtube. did your 1 1/8 headset not fit the headtube or something? what fork (how big steerer diameter) are you trying to put on there?

Kev

There are adapters, basicaly like shims that fit in a 1 1/4" head tube to adapt it to a 1 1/8" fork. I believe it is cane creek that also makes a 1 1/4" headset to that will make it work with a 1 1/8" fork.

TotalKos

The fork is a Judy that is 1 1/8". The headset is 1 1/8" and it doesn't fit the headtube.

Kev

Cambria sells a headset reducer, if you're headtube is 1 1/4" here is a pic of it..

Mr. TotalKos,

I think I get the picture! You're trying to install your 1 1/8" headset on a 1 1/8" headtube without using a headset press. Therefore you're assuming it doesn't fit. For a six-pack from your local micro-brewery, am I correct????

tFUnK

does the headset fit into those adapters you posted in the picture? do those adapters fit into the head tube?

when you say the headset doesnt fit the headtube, do you mean the headset is too small, or do you mean it's too big. if the headset is too small for the headtube, then the headtube takes a 1 1/4" headset. if this is the case then you can get headset reducers. if the headset is too big for the headtube, then you probably got a 1" headtube and i think you'd either need to swap steerer/crowns or get a new fork altogether.

DING...DING...DING... ROUND 11....

Mr. TotalKos.. Your ATX 890 has a 1 1/8" or 1 1/4" headtube??

TotalKos

OK I am almost positive that the headtube is 1 1/4'. The only other possibility is 1.5" but apparently that is rare. My 1 1/8" headset would fall in the headtube if I let go. The headset does fit (not by hand) with help from those adapters in my picture. So I'm pretty sure that I can use the adapter I have or the reducers you guys have told me about to fit my 1 1/8" headset into the 1 1/4" headtube.

A new question is how much does the tool cost to seat the headset in the headtube? Are there alternative way of seating the headset? Thanks already for the help.

roadfix

DING...DING...DING.... ROUND 12...

OK.....You can install your 1 1/8" headset on your 1 1/4" headtube by using headset reducers that Kev suggested earlier. You would need a headset press to install top and bottom cups onto the headtube. I'd suggest you have your LBS do that for you. The tool is not cheap but you can easily make one like I did using a long 3/4" thick bolt, several thick washers, and a nut to press the cups onto the headtube. But don't attempt to install this yourself with a homemade tool unless you know exactly what you're doing!! Let your LBS handle that part....

TotalKos

DING...DING....DING..... THE REF HAS CALLED THE FIGHT.

"Put this one to bed folks!"

Thanks

FWIW, I still think the headtube is 1-1/8". What year is the bike? Every specification for the Giant ATX 890 lists it as having a 1-1/8" headset as stock. I wouldn't think that Giant would ship the bike stock with a headset reducer so I would assume that the headtube was also 1-1/8".

roadfix

But one reviewer on MTB Reviews mentioned or complained to the fact that the headtube on this frame was "slightly larger than 1 1/8 inch" or something to that effect....

khuon

That's truly odd. What was Giant thinking?

khuon

Hmmm... it seems that there's some mention of the ATX 890 using integrated headsets. That might explain a few things. I personally would not attempt to use a standard threadless headset in a frame designed for an integrated headset. I do however believe there are appropriate adapters (reducer that is also a cup to fit inside the integrated headset space) made to do just that. From the pictures of your headset adapter, I'm not sure those are the appropriate adapters.

Check out this link.

Unless you're really in love with the headset, I think it'd be better (and possibly cheaper) to just buy an integrated headset.

roadfix

Ahh.....now that makes total sense.
