Can anyone suggest a gyro friendly headset? Something new for this?

What's on it now barely gives any threads for the top nut.

Yes, its pressed in tight. I just think its the headset. Is there a new lower profile one?

I also realize the chrome gyro part is upside down. I am just worried about threads.

Thanks, appreciated.

Supposed to omit the washer.

Yep.
Take that washer out of there (it's not used with a Gyro) and you should be good to go.

Even without the washer there is still not alot of thread.

Yes, im my original post I posted I know the rotor bearing is upside down. It's a test fit

Any one?

There will be less thread with any headset, there is no way around it. It should be sufficient.

XJguy · 2012-11-05 8:38am

I shouldnt say there is no way around it.....there are ways but would require custom manufacturing, which I considered myself, but since I am not a professional rider and my bikes will not be ridden very hard and will b e maintained meticulously, it would be a waste.

Brad4130 · 2012-11-05 8:58am

You could try a Tioga bear trap 2 I believe they have a lower " stack height " which is the total height measurement of the headset .
If you still have the YST box I believe it's printed on the outside .

As others have pointed out there are custom manufacturing options to squeez out a few extra mm .

I just wanted to know for sure that we are all in the same boat. I have ordered an MX2 and will try it. The YST which is on it does not have measurements.

Anyone know if the steer tubes are longer say on a GT PFT that came factory with a gyro?

PS. This bike factory should have come with a rotor.

Looks like you have a gap between the headset cup & the headset adjusting cone. Try turning it a few more times ( as long as the forks still spin smooth). Take out the washer cause the upper cable stop of the gyro will take its place.That should give you a little extra thread for the headset locknut.

XJguy · 2012-11-05 9:44am

Also make sure both bearing races are in the right way. I see your top one is, but I cant tell if lower is.

I had the SAME problem installing a GYRO on my SE Quad FS. I eliminated the washer and I still only had about 3 threads to work with. It never broke on me, but I also wasn't thrashing hard on the bike. It seems the old 80's SE forks were a bit shorter thread-wise. I tried my standing gear forks on my Quad and a Redline... same issue with both.

But in the end, even with only 3 threads to work with, it worked and held.

Brad4130 · 2012-11-05 10:17am

Oh yes
Make sure you have the beating in correctly
Bottom - balls up
Top - balls down

Double check this before tightening or you can re-form the bearing races .

Yes you could have a point as this bike was designed for a rotor then the steerer could be a MM or two short .
Omitting the lock washer is one trick .

Another it filing your upper lock nut flat to remove the non threaded end , so it starts on the threads this will help .

Good luck with the project .

Oh FYI - measuring steerer tubes from differnt bikes won't help as most early frames had varying Headtube lengths .
I would suggest facing the Headtube or crown race on the fork a bit but you already have everything painted so that's a no go .

Good luck

Guys these are the answers I was looking for.

I am going to try another headset and MX2. It looks a bit flatter.

Washer will be removed and the gyro spinner will be right side up. I will tighten and adjust as per instructions above.

Thanks guys. I will post an update later this week.

Update. I pressed the bearing caps in more. It's alot better and as good as it gets I guess. Next time rotor!

Thanks guys for the info.
