Hi there,

I just picked up a Stumpjumper Bi-Plane Fork on ebay for a 1983 Stumpjumper Sport that I am rebuilding. My frame is a 23" and I think the fork steerer might be too short.

The headtube is 8" long and the steerer is 8.5" from the top of the crown race (installed) to the end of the threads...

Any ideas if this is going to work?

I have a fork for sale if the answer is no.

Thanks

I'd say it's gonna be too short. A short headset stackheight is going to be at least 35mm, and if you only have .5 inches to work with, you've only got about 12.5mm.

no go, you'll need length for about 1.5 inches of headset.

If you have a donor fork, a decent welding shop could lop it's steerer off, and weld it onto the too short fork to create the proper length. Did it myself with a fork I got a deal on, works fine, done properly.

Note this is not the "proper" route (which is find the right fork), and purists likely wouldn't like it if you were selling them the bike, but it will work just fine. Just make sure it's low enough so as not to interfere with the quill fully inserting.

Thanks for the info. The seller told me that the fork came off a 23" Stumpjumper so once I get my hands on it, I will definitely know for sure.

It's so much easier when you find a full bike... :madman:

If you do decide to sell it, drop me a line.
