Well.. based on today's ride, I have to disagree. It was noticeably better with the stabilizer on a 25 mile loop today. It doesn't eliminate the issue but I felt much better. I agree that there is much more benefit as the steering angle increases, but the bungee is preloaded with a lot of force so the torsional forces are fairly high, even with low angles. I'm going to leave it on for now.
Yea, this is exactly what I was going to suggest. Elastomers have very nonlinear spring rates, hence "preloading" is a must. Or use a 'real', metallic spring.
An other benefit of metal spring is that it should last pretty indefinitely, unlike must rubbers. I'm not an expert on polymer chemistry, but some polyurethane rubbers are extremely resilient and have extremely low creep and set - and in fact used instead of steel springs with better effect... however it should be up to Cruzbike RnD to find those compounds and apply them to their bents.
So far they deal with the problem mostly by ignoring that it exists, as per my impression .
