Can I thread a Soma 1" threadless track fork?
 

I just picked up a rush frameset off ebay for pretty cheap.

It has a threadless fork however and I want to thread it.

Are their threadless forks just unthreaded versions of their threaded fork, or do they have thinner steerers?

Technically, you can thread any threadless fork (rather, a skilled bike mechanic can). In practice, it will most likely be cheaper and easier to just buy a threaded fork.

I'll trade you my threaded fork for your threadless fork...you will have to get a new headset installed in your frame for a threaded setup

So the steel is not thinner? Cheaper and easier to buy another $100+ fork?
If you have a threaded track fork that will fit a 59 I am Prolly interested. What is it?

The steel is thinner, yes. But I wouldn't worry to much about it, Mr. Hoy. And if the only forks you can find are $100+ you need to refine your shopping skills.

Cool, I'll look into it more once I'm holding it.

Yeah, I was referring to the Soma one, which is Prestige and pretty nice. $100+ for a fork is questionable though.

I just noticed someone posted a link to the bike I bought in the Craigslist thread. I got it without cockpit for considerably cheaper.

Here's the link till he takes it down: http://dallas.craigslist.org/dal/bik/2178176816.html

Threading a threadless fork is a difficult, costly process and a lot of shops won't even do it. Extending the threads on an already threaded fork can be done much easier.

Just buy a new fork. Here, I'll do the work for you:

I just paid $60 to have a fork threaded further down but a few shops I tried didn't want to do it.

Right, and yours was already partially threaded.

Ya from the research I did it is very difficult to thread one that is threadless. I was told to try to find a machine shop. But I also recommend selling your fork and buying a new one that is threaded.

Cool, didn't realize it was such a *****.

Thanks guys, Ill figure something out.

I'm really surprised you guys are finding it that hard to get a fork threaded. A few years back, I had a KHS Flite 100 fork cut and threaded for $30 at a LBS. It wasn't a big prcoess at all.

Try sticking a quill stem in your fork first, and if it doesn't fit, you'll have to have the fork reamed out. Most local bike shops won't do this, and I had to take a 1" threadless fork to a local bikebuilder to have them ream it out (they also built the fork). I'm not sure if Somas are typically thicker than usual or not due to them being threadless.

If you do have the local bike shop thread your fork, make sure you bring them the headset and the frame so they can cut the fork to the same stack height as your headset. Your best bet would be finding a local bikebuilder and having them do this for you, 9 times out of 10 they'll be more precise.
