Went and measured the longest 1-1/8" threaded steerer I personally have, about 8.5" and that's the longest non replacement fork I've ever seen. The frame it came off was gigantic by mountain bike standards, 23" or 24" at least.

Okay, tomorrow I'm actually going to go measure my head tube and steerer. We got about 18 inches of snow last night, so it's a slog getting out to the shed. One of these years I will remember not to store my snowshoes in the shed.
