threaded forks and stack height etc....
 

picked up a unknown frame fork setup. I believe the frame is german and the fork that was put on the bike is a pinarello. The pinarello is much too tall for this frame but the previous owner didnt want to cut it down. He as a tall guy riding a small frame and thought one day ....he might find a bigger more sutiable frame for it. Anyway....the top nut threads clear through exposing the threads on the top. I have never seen one of these crown nuts before. There is about 1 inch of threads exposed.

Could i use spacers under it to clear this up? I might just leave it. Looks funny which is why i thought i would ask. I dont want to cut the fork either.

Yes. (As long as the lower cap/race/nut threaded down far enough.) It is not uncommon for (canti) brake housing stops, reflector brackets, stem shifter brackets, basket brackets, and etc. to be between the headset's threaded pieces.

I do not see why you could't, unless the fork is now bent from riding it that way.

I hating cutting forks short and unless the customer demanded it I never cut them any shorter than a half to full inche of extra space. that gives you alot of options if you ever need to replace the HS and give you a bit more height on the stem.

here is what im dealing with. Ive never seen a nut anywhere that allows this but the previous owner found one.

THe exposed threads are just less than an inch

Space it or cut it.....either will work.

scale, I have a partial set (I used the 3 mm) of these: http://www.nashbar.com/bikes/Product...1_10000_202347 if you need.

It's not unusual to use spacers between the adjustable cup and the top locknut on a longer threaded steerer.

what kind of frame is that? i would almost ditch that whole HS.

Spacing it out it is. Now to stop by the LBS and get the 1inch spacers :)

kind of frame? hehehe....thats a good question.

im still hunting that one down. I do believe it is a german frame. IT has some interesting german tubing. It is light....

thats about all i know. I want to say it is a 80s Patria WKC but that is yet to be determined. I imagine those are not too common in the states.....

If you google it.....you dont come up with much. Ive found a few photos that match (top tube eyelets etc) but no definate answer. Ill post more pics soon.

I too would suggest replacing the headset and adding spacers. Make sure the LBS attendant doesn't give you 1 1/8" spacers by mistake.

Yeah................I'd dump that manky looking headset if I were you and start fresh and clean.....with spacers as needed....
Unless the steering tube is way too long, I'd try to avoid cutting it. Cause if you end up cutting it too short for a headset you might want to install on a bike in the future, you cannot bring the legnth you need back.

Pics of bike and fork?

Ill post here .....to a new thread im starting about the bike project. It will contain pics.

It will likely be tonight sometime as it is too nice and i just got off work. Time to ride.....

I bought a road bike for my little brother recently that had a suspension fork. I removed it and installed a steel fork and rather than cut it I removed the anodizing and polished three 10mm spacers and a couple 2mm spacers. I think it looks pretty good with the simple Tange Levin headset.

here is the thread i started on the bike if anyone is interested.....

so is the Tange Levin the way to go? Seems to look about period correct....and it looks simple. ANy reason not to go down this road? Looks like they can be had for about $20.

That's exactly how I set up the RB-1 when I replaced the fork -- an additional 2cm.

what is the difference between the NJS and or CDS version of the Levin?

I kind of like the TEOTWAWKI zombie-fighting Mad-Max exposed-thread look.

^Not familiar with CDS but NJS is just a certification that the part is cleared for use in sanctioned Keirin events.

You pay a royal ransom for the NJS stamp on the part. In part, due to the trendy demand from fixie fanatics.
