So I realized I posted that other message a few times. I removed the old ones with out comments
Lemmy wasn’t showing them so I kept trying and now I see there were a few of the same posts.
Anyways,
Problem: Speed wobble over 25mph and during specific road surface and load distribution scenarios.
Attempts: Elastic cord tensioner scheme.
- Used a old dropbar clamp to make a attachment point on the left side of fork to mirror steering linkage arm on right side.
- Adjustable tension loop to frame. Max elongation set at furthest turning point. Created feedback spring effect that was fine but felt funny. Removed.
- Adjustable tension loop from left bottom of frame to steering arm. Goal was to put tension on system to reduce harmonics. Still installed
Solution: Replaced headset top half with Cane Creek Viscoset ZS 44/28.6
Big thanks to Kash at WarmPlanetBikes for the tip!
New top speed is 43 mph downhill. *not with kids of course…
