The clamping mechanism on the ZX1 is designed for a 1 1/4" camber tube. It should clamp firmly but still allow the camber tube to rotate inside the clamping. It's possible that your Kuschall has a smaller, possibly 1 1/8" cambertube causing it to shift laterally too easily. Spinergy may have a thicker carbon fiber bushing to help with that. I've ...
Originally Posted by robotnik I've done some adjustments on my ZX too, - I've removed the anti-tips, it helps on small curbs, but you'll have to get used with the "dive" of the armrest. Especially with the joystick's side when you use the motor's brake, it can be surprising... - I've removed the high adjustment nut stop of the clamshell, near the proximity sensor. Now I can raise my chair to the maximum without going in crawl mode, - same problem of ZX sliding laterally on the camber bar. I've used ...

We have a Anderson sliding door; there's about a 1" drop from the flooring to the sill the screen tracks are on, then 1/2" onto the bricks of the patio. The friggin thing gets stuck! I try raising the chair/NG; I lo0wer the chair so the wheelchair tires ...

I agree, it could have just been a last minute mistake, and better to give them a chance to respond. Whatever you do, don't let anyone back down from getting the chair you designed and signed off on. Just as a note, should you ever want to consider a ZX-1 power add-on, it would probably be impossible with that added bracket.
Originally Posted by triumph I have a zx1. Are you saying you want the clamshell to only partially "grab onto" the wheelchair axle bar?

Don't know if that's what you're after, but if so, have you tried to only partially attach clamshell with the clamshell actuator button? I don't do so until I get to a bump - at that ...
