« on: Today at 04:41:13 PM »Ran into a snag on size S frame/fork. I cut the fork slammed for only the 12mm headset and the expander plug is too long. There is a ridge on the inside before a not smooth section 40mm from the top. The plug is 50mm. I think if you have a 10mm spacer + the 12mm you will be fine. I'll have to go get a shorter expander plug. Shouldn't affect most except those slamming a size small
Thanks for sharing this info @edfungus. I didn't had this surprise on the radar.
I wonder if the ridge can be filed off, I doubt this is structurally load bearing. Surely the expander plug should make contact on the upper straight part, not be stuck on a remnant of the ridge, so might be difficult with a file.
I checked an old fork, the non-smooth section starts roughly where the outer diameter is expanding.
