Hi, I have had my radial 36 for a few months, enjoying it greatly. However a problem has come up in the last few days - there is a rubbing in the hub. Some resistance, it comes and goes. Twice it has come surprisingly quick and strong enough so that I fell off - major drag. When its at its worse you can hear it grinding a bit.
I have taken it apart a bit and looked around but didn’t find anything too suspicious…a tiny bit of grit and rust makes me a bit nervous. I don’t have a crank puller to get in deeper.
I plan to take it into the shop this week, but of course they have never worked on a uni before, so any suggestions would be appreciated. Guessing I might need new bearings?
