The ICE trikes split I think to allow different configurations [ i.e wheel sizes , but don't quote me on that ]
It has been attributed to poor maintenance rather than a design/build problem with the trike.
This was in post #64
We are spinning in a circle.
Yes, the rear triangle of the VTX was crooked
Yes, the owner should have checked the clamping screws
No, the clamped tubes are not a bad design
No, oval tubes of the required quality are not available
(oval tubes, on the other hand, would be a bad design, a bit of dirt or rust and then nothing moves anymore)
The main cause of the fall were simple driving errors
Did I forget something?
Oh yes:
Would the special experts who "bang on" the clamping screws also please make sure to use screws of the appropriate strength class? My suggestion would be M6 screws of at least grade A4-70 (even A2-70 or 8.8 are too soft). If you "bang on" please use galvanized 10.9 or better 12.9 screws. Then don't whine if you rip the soldering points off the frame tube.
