I bought a used Nimbus 24 Muni a while ago. The wheel always felt slow to me, but I thought it was the heavy tire. However, I would spin it and it seemed to slow more quickly than my other unicycles. So I thought maybe the bearing caps were overtightened. I loosened them a bit and sure enough, the wheel definitely spins longer and rolls better. That’s the good news.
The bad news is that while spinning the wheel I can hear a fast ticking sound which I think must be the bearings. It’s a fast tick. And then when riding downhill I get clicks coming occasionally which I didn’t hear before. What to do? Should I just go ahead and replace the bearings? Could I have a clicking noise due to the bearing caps being too loose now? I don’t feel any play with them a bit looser - I think I loosened by about 1 full turn of the cap bolt. And maybe the click that I hear is another issue but it is suspicious that it started shortly after the cap bolt was loosened.
And is the bearing ticking noise anything to be concerned about? I do not hear this on other unicycles, so it seems wrong.
Any advice appreciated. Thanks.
