Just did my first 7k commute with the K50 tire--definitely an improvement. It took some time to get used to the different feel, but it's significantly better on ice/hard-packed snow. For the road conditions I'm riding on I wouldn't even want a faster unicycle in winter--I don't think I ever hit max on the V8. I'll try expanding my stance a little and see how that improves stability. Where I still had the most trouble was with ridges (like the edge of a plowed section), or really bumpy stretches. Since some of it is blown snow here today I actually had to pick the V8 up and walk it over some sections.
My next questions have to do with other gear--with me traveling in winter, and my eyes getting quite cold, as well as wanting to move in spring/summer/fall to a faster wheel, I am thinking a full-face helmet makes sense. When I picked up the K50 at Canadian Tire I looked at snowmobile helmets on clearance. What do you wear as a helmet? I'm not wanting to spend $200. In winter I can only assume a snowmobile helmet would be great, but I feel like I'd overheat in summer and never want to wear it. But the advantage in winter is I wouldn't need a tuque or anything underneath.
Also, do you wear knee/shin guards, elbow pads? If I go above 30km/h I think I want to move into that area.
PS. I'd be happy to move this conversation to messaging, but I don't think I can (either the platform doesn't have it or I can't because I'm a newbie).
