I used to commute on my Haluzak Horizon all the time back in the 90s. I've just started getting back into it now - I've got just over 200 miles on it since I put a new battery back in the computer.
This morning was rainy, but a very peaceful ride in. It rained on and off all day and for the ride home it had stopped raining but the trail was covered with leaves. As I was coming down a descent into town on a trail near the end of my ride, the bike started feeling squirrelly - sort of wobbly in a way I'd never felt before. I thought it must be the leaves being very slick. It wasn't. It was the nut on the front of the steering linkage that had come off and the bolt was working loose. I found that out when the front wheel decided to turn all on its own and dumped me on my side. Luckily I was still slow cause something didn't feel right and I just slid a bit - a little on wet pavement and some on the grass slope down the side of the trail.
I've repaired it and it appears good to go. I'm just so thankful it happened at that point and not during the very last leg of my ride where I'm on the road with traffic!
