So, last night I got a bit of time to try and improve the Kona. After a bit of trial and error, I got what appeared to be a dead-straight belt-line. Spinning the cranks inside, everything stayed straight and true, and a midnight jaunt along the back lane, everything stayed in place.
This evening, I went out to test it. Tentatively spun along the road into town, no problems, tried out of the saddle sprinting, everything’s fine. Detour into the hospital car-park and down the steps, all good. Dare I say, the bike seems Fun, belt or no belt 🙂
One case of “ratchet-slap” from trying to wheelie, easily solved with a snubber I think. Head uphill so I can point the bike down a rougher section to see how it copes. Out the saddle, power down and BANG! Belt off. Put it back on and set off, this time watching the belt. Sure enough, after a few pedal strokes, its moving sideways off the rear sprocket. So clearly, the increased tension of getting me uphill is enough to put a sideways component on the belt and pull it off. Hopefully re-shimming the cog will help. Job for tomorrow night.
But aside from that the Kona A is a right laugh, and the belt is effortlessly silent (except when it comes off).
Question for Epicyclo – would a snubber help and would increased belt tension help?
