Unicycle rollers 20:48 
Wanted to do something today, and by the time I got around to it, this was all I could get up the motivation for. I'm, uh, tapering for the Billygoat. Yeah, that's it. Anyway, it seems like maybe the eccentricity problem on the rollers has gotten worse, because it looked like the axle was rocking back and forth to the tune of nearly an inch (which, needless to say, didn't make riding easy). Some of that may have been due to the tire needing a bit of air, which made it bouncier than it should have been. I can detect a bit of unevenness in the rear rollers when I spin them and hold a thumbnail against them, but it's surprising how much that translates to in terms of the effect of a wheel that's rolling on them (although if I sat down and did the math, it probably wouldn't be so surprising).
