Steering dampers:
Usko has such a steering damper on his Hipparion trikes and seems to be very satisfied. On the other hand Nobuo doesn't seem to use a damper and he goes fastest of them all...
Locking the pivot is suicidal, in my view.
Kamikaze-like!

Dear Pythoneers

Locking the pivot would prevent the Python from steering at all, (straight, 
fast but very dangerous) wouldn't it?
Leaning on a conventional bike uses the trail of the front wheel to turn. Zero 
trail and you have to steer with the
bars, no self-centring, leaning does nothing. Although you're not actively 
steering, the wheel is still turned
relative to the plane of the frame to give an arc to follow.

I've seen some of you use a rubber block steering damper, which helps wheel 
flop and limits steering extremes. It
can't help with high speed shimmy and oscillations much though. I know they are 
very expensive new (300 Euros), but
has anyone tried the oil filled piston steering dampers used on racing 
motorbikes to stabilise the front wheel. They
lock against any quick movement but move with steady loading, the opposite of 
suspension forks.

All the best

My question is: has anybody ever thought of putting a lock on
the pivot before going downhill? Turning at high speed is
done by leaning anyway.
