Surley Steamroller threaded forks
Hello all-
I've seen this question posted before, but never got the simple answer I'm looking for.
I have a Surley Steamroller with a 1" threadless fork. I'm interested in switching this to a threaded fork, for the purpose of getting a very high-rise quill stem. I really don't like the look of the threadless stem extensions, and the performance level of a quill stem is good for my purposes.
Since is doesn't look like Surley offers a threaded Steamroller fork anymore - has anyone done this conversion who can suggest a suitable threaded fork for sale to fit this frame?
Thanks in advance for the help.

If you cannot find a decent usable fork for your needs, and IF the steamrollers steerer is 1" with an ID of 7/8" it can be cut and threaded to suit your needs. If nobody local is able or willing to do the job, I can. Let me know by email c/o the Chain-L site below if it comes to that.

Go to the Surly site (or email and ask if not posted) and check the axle-to-crown and offset measurements. Take these two figures and match them up with any other fork you are considering and it should be good to go.
Surly:
Axle to crown (1"): 368mm
Offset: 38mm
Soma:
Axle to crown (1" threadless measurement): 368
Offset (threaded number): 41mm
The bigger offset will lead to a slightly more active/less stable steering. I would just confirm with Soma regarding the AtC measurement before ordering, since they don't list it for their threaded 1" track fork.

Do not do that, the tubing used for steerer is not thick enough to have threads cut into it. Says so on surly's website.

I would be surprised if Surlys ever came with threaded forks. I'm thinking that a replacement threaded fork is the best option here.
