Giant XTC Composite Headset issue.

Posts: 8,207
Im trying to get a headset to fit my carbon XTC frame which takes an internal headset. I've lost the original headset that came with it and bought an FSA Orbit IS2 CC off CRC.
The bearings are exactly the same as the original one that came with the frame. When the bearings are placed into the headtube however, they sit far too low down.
I assume this means theres something missing from inside the headtube?
Anyone know?

Probably some of the carbon dissolved in the rain. Free bump anyway.I don't do smileys.

Yeah, you've not put the cups in. It takes a semi-integrated from the look of things as there is no bearing seat on the inside of the headtube, you need something like this:
Click the picture to go to CRC.
Basically if you had a proper integrated frame there'd be a chamfer for the bearing to sit on. As far as i can see there isn't hence you need the internal cup ones. If you order the appropriate cane creek headset then at least you've got spare bearings!0 -
as above.
Andy you know i have work to do.
measure the diameter and compare it to the Standards on Park.

but the bearings he has will nor fit the correct headset "Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

It's not semi integrated. It's an internal headset.0

Have you tried the cane creek headset finder? http://www.canecreek.com/headset-fit-finder
will have details for Giant frames.0 -

that is the same thing. a semi-integrated is an internal or zero stack headset.
so what is the measurement?
cant see any taper seat..... for an integrated headset (no cups)
here is Chris's integreted head tube.
from the FAQs "Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Thats what I'm trying to find out. There used to be an extra bit inside the head tube.
It's not one that the headset cups press into the inside of the head tube but there was something else in the headtube that is now lost.0 -
I know you are convinced that there are no cups but I found this: http://forums.mtbr.com/showthread.php?t=352096
Or
Looking at your frame it seems as though there has been 2 different parts in that head tube as there is a dark ring just above the step which is about 1/3 of the total bore depth.
It could either be a spacer or some sort of crown race?
Is the hope one is just assembled like the pic to keep it all together? or is it a spacer? http://www.wiggle.co.uk/p/cycle/7/Hope_ ... 5360031545
What is your head tube bore diameter and depth?0 -
Using the old Hope site (new one is crap):

Part 2 is indeed in the correct place in the picture and could be what you need?0 -
2006 XTC Composite, came with a FSA Integrated headset according to Giant webby.
Same frame?

Yeah same frame although I bought frame only.0

Thats almost certainly it!0 -
So are they headset specific or will a hope one do the trick?0
-
I suspect they are specific to the angle on the bearing for the hope but there may well be a 'standard' for frames like in the FAQ pic above where the taper appears to be machined into the headset.
cane creek seem to have their own standard: http://www.canecreek.com/manuals/Headse ... ctions.pdf
maybe Giant and others use the angled bearing seat to ensure they can be used with different standards.
If you can get the angle of the Hope ones and the ones you have then you will answer your own question I guess. Good luck finding out the info though.0 -
Cheers for your help!0

still learning all of this tech stuff but maybe one of the bearing angles is or also corresponds to the seat angle as well as the contact angle.
"Hope Integrated Headset: Integrated headset for road/lightweight XC MTB bikes. 36/45 deg bearing size 61g 41.4mm head tube bore 10mm depth into frame (only)"0 -
ahh the useful Park headset info:
http://www.parktool.com/repair/readhowto.asp?id=68#is
I was right, the 36 is the internal contact and the 45 is the frame contact angle. So if the one you have is also 45 (should say on the bearing) then the hope one should work.0 -
have you measured the bore yet?
and giant used to provide a reducer that allowed a standard headset to be used rather than a Zero stack/internal one."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

been having a look and http://autobus.cyclingnews.com/tech/200 ... cker_giant

I've ordered a pair of Hope bearing seats. Will report back.0
