this keeps happening with an other bar (gong, in much better condition, see photo)...
I had both hands on the bar for sure as i still held it with two hands after last eject.
Then I had a day without this happening. That day I finally had a breakthrough and started to ride upwind. So i thought that's it, it must have been caused by my uncontrolled waterstarts.
Next day rode 3hrs without an issue, fun (trying to learn transition). Bit stronger gusts but nothing extreme. After a fairly strong pull when tried to transition, boom, loud metal click sound and eject again. Bar is in my hands but had to let it go as was pulling too much. This time quite far from shore. Luckily a kiter picked my kite and a windsurfer dragged me ashore, saving me a 40mins swim.
The QR was in the state as on the photo.
As much i can recall all cases it was a very strong pull when it happened.
Is it possible that both bar have an issue? Or am i doing something wrong?
