Replacing threaded fork...
Good afternoon! I need to replace the fork on a lugged steel road bike I'm building up for light touring purposes. It has a 700c (bent) fork on it currently, and I'm struggling to find a 1" threaded fork in 700c size that has enough clearance to run fenders and reasonably wide tires. It needs to have a steer tube length of 200mm, which also narrows the search significantly, and I'd prefer a lugged design. I'm wondering if using a 27" fork would be an acceptable option, using long reach brakes. It seems on the positive side that this would give me extra clearance for the front tire/fender, but on the possibly negative side, general frame geometry could be thrown off. It currently has a flat top tube, so a slight downward slope to the rear would be acceptable as long as the ride isn't greatly compromised. Your input would be much appreciated. Thanks!!

I replaced a damaged 1" threaded with a very nice used one my LBS had kicking around. It was much better quality with Reynolds 531 steel but the geometry was not quite the same so I lost some descending stability.
Have you considered a move to threadless?

I know that you can use 700c wheels on a bike designed for 27", so it seems like you could make it work with a 27" fork...but I haven't tried it, and I don't know if it would affect the handling.
You might also keep an eye out for threadless forks, although there aren't too many of those available in 1" size. You would need to get a new headset and stem, but that might open up a few more options.

I am in the market for the same 1" threadless fork for touring and would like mid-fork attachments for a rack/panniers and am having NO luck finding anything...
The 27" fork looks like a good alternative...what is the reason for the 27" terminology? What does this mean?

Maybe not the cheepest option, but Mercian will custom build you any fork you want: https://www.merciancycles.com/home/1/...mes-cycle-shop
I ordered a fork from them, for my Dawes steel touring bike, and the product came out very nice. You just need to make sure you send them all the technical data.

27" wheels have an ISO standard diameter of 630mm vs 700c wheels which have an ISO diameter of 622mm. So the 27" fork is made for rims that are 8mm larger in diameter than 700c. Besides the possible difference in geometry one would want to make sure the brakes will work if using 700c wheels with 27" rims.

Thanks for the input! I have considered going the threadless route but was leaning toward keeping with threaded so as to keep the quill stem (mostly for aesthetic purposes). I know there are adaptors for quill to threadless stems.... Does such a thing exist for threadless to quill?
This seems like a decent threadless fork offering from Soma: https://store.somafab.com/soclcucyfo.html

Surly makes the Cross Check fork in 1" threadless. It is lugged and they have a version with mid-fork eyelets. Might work for the O.P. but like it was said before it will require a threadless headset and stem.

I tracked down an adapter (which includes the headset), if anyone else may be interested. https://store.somafab.com/soqu.html

Left to Guess .. It's for 9/8" threadless forks?, when you get it, let the list know..
Sean may be best served by getting a fork Made, by a frame builder.
In addition to UK imports, contact Bruce Gordon, In Petaluma California.
Touring frames and forks is what he does a lot.
Perhaps one of his BLT forks will be suitable, BG designed TW import.
they are made to fit Bruce's excellent low rider racks
[my racks have gone thru 2 frame changes, in 25 years, still fine]
1" threaded, quill stem on the BG bikes so that may suit your needs..
