Nikyo Headset/ GT Performer Fitting problem...

(1/2) > >>

funkyfresh:
I have a black Nikyo headset and an 85 performer.

 Got the local bike shop to fit the cups, but they say the crown part is the wrong size?

I tried myself and cannot knock it on, even after freezing the forks/ putting crown in hot water...

The shop said something about US v Japenses headset sizes, and that i would need to reduce the diameter of the forks using a special headset tool?

is this right, or are they quite often very very tight?

i dont want to start filing etc, if i really have the wrong headset...

Cheers

MartyC:
My Nikyo was a buggar to get the cups into the frame and really took some effort but the bottom race on the forks went on OK.  When I worked in a bike shop we used to use a short price of scaffold tube to get the races onto the forks, maybe it just needs a bit of brute force  :-\.  You could try filing the inside of the race to open it up a bit, I can't imagine you'd need to take too much off.  Have you measured with a pair of vernier calipers to see how much it's out by?

funkyfresh:
Well i used Dremel type stone to open up the inside diameter of the race, but it was still a sod to put on. In the end even heating quite hot wouldn't help and I've managed to spit the damm race now...

So basically, did i Have the wrong headset size for the forks? is there a Jap size and a US size?

Any suggestions welcome?

And anyone with a blue or black headset for sale, LMK....

I hope I will be lucky in fitting a black Nikyo headset in also.. a GT PP 1985.... :buck2:

if not .... I will be the biggest  :Aresehole:.. because there was this topic here and I didnīt search ...

I have a GT Epoch in metal top cap and I canīt fit the Giro detangler systems (the cups are too large for the Gyro to slide over).

so.. I bought the Nikyo in hope that it solve the problem... but now... i think that I should...  :bondage:

Funky fresh... what did you do????

regards,
