Hahaha, I think he only got pictures right before it happened. I'll ask him. Thank you for your kindness - I felt horrible after it happened, and I still did until now.

I thought we were gonna be okay after that initial bump as well, but something did seem to get tangled up. I didn't notice it at the time, unfortunately. I think you're right about it not being the handlebars because I didn't spot your bars in mine. But it was just this incredibly strong tugging feeling from the left that brought me down that I assumed that was it.

In hindsight, I should have just ran through the unpaved section of the road to tighten up my line and make some room. I'll definitely take the chance to learn from this as well.
