I'm sorry about your accident and the resulting slide. I'm at ATTGATT guy, too and I'm very glad that you're in the club!
Can you describe your lane position when the the slide began? I tend to try to ride in the car "wheel tracks" as they are generally more clear of gravel.
Your photos show less gravel than we normally see on a "trashed" corner in the SE. What is the lesson for us? How could the slide have been prevented?
Thanks for the feedback and good luck on your repairs.
The corner was a right hander and I had started the turn close to the center line and aimed toward the inside car "wheel track" at the apex. As I approached the apex I believe I was slightly out of the car "wheel track" right where the gravel gets pushed from the car tires. The gravel was unnoticeable because it was the same color as the road and very small (it didn't leave a shadow on the road).
Sorry to hear about the get-off and attendant bike carnage. Glad you're OK though.
Would you mind telling us a little more detail about how you went down on the gravel? I couldn't even see any gravel in your still pictures so I can understand how you wouldn't while riding. Did the front end wash out or did the rear let loose? I'm thinking the rear maybe slid out resulting in the subsequent high side and bike flipping. Is that right?
I guess maybe the takeaway is to ride the outside wheel track in your lane all the way through the corner in questionable road surfaces (possible loose stuff) rather than late apexing and crossing the center of the travel lane on a lean.
