Maybe a Ti bolt that fits tight inside this one? With an hex nut the same size as the allen key needed on one side?

Thanks for the suggestion, but I dont see anything that would fit. I was going to try to find a sex bolt with a 10mm OD sleeve, but those are hard to come by.
I wound up ordering a half meter length of 10mm OD 8mm ID Titanium tubing, which I should be able to press fit inside the new bolt. I've done similar modification to rear hub axles, and it helped substantially. Just one of the many perils of being a clyde cyclist.

Mine came loose. If yours was loose this might have caused the failure.

If this was in response to my broken pivot bolt, it was not loose. It was quite a challenge to remove the threads after the bolt broke off. If anything I suspect that it was too tight, and it failed on a particularly cold day (single digits F). But who knows if contraction played a role or not. Ive since epoxied a short length of titanium tubing into the ID to reinforce the bolt and hopefully prevent future failures.

Ironically my P8 bolt broke in the exact same spot. I ended up finding a standard black oxide steel bolt with the proper length and thread pitch and turned the head down to match the taper.
