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…
I get a wobble in my Yuba Spicy Curry with kids on the back around 15-20 MPH. Have to go no hands or very light touch to feel it. So far it is not a big deal, but it is concerning.
You want to fix it? Maybe I can help
Yes! What do you suggest?
Send a picture of the underside of your cargobike, steering system, and front headset
I’m not sure if these pictures are enough. Let me know.
It looks like it’s a match. 1.5 inch external bearing headset.
That’s what I have.
Can we send DMs here?
Amazing. I think I have a spare of the ViscoSet dampener headset that fits your headset. Any chance you can get share model info for the bike or the headset.
I’ll send you this spare if it fits
