Freewheel wobble - Problem?
I have a Dura Ace 13-28 6 speed freewheel that I intended to use on my Eroica bike. I used it last year on my Tommasini with C Record hub, Super Record RD and crankset. Everything was great with it last year but when I apply max brain cells, I think maybe I can remember a little skipping on the small cog. Now as I’m testing out this years ride on a Record hub, Super Record RD, VO compact crank. on test rides I get a lot of skipping on the small cog, occasionally second cog. When I look at it in the stand, freewheeling, there is a lot, and I mean a lot of wobble, as much as I’d guess a couple of mm of lateral movement. I thought maybe it was a problem with the hub threading, maybe slight axle bend so phase two, I move the freewheel over to another Record hub, used with a 13-24, on the same bike with perfect shifting, and the same wobble is there. Weather is crappy, so I can’t road test right now. So:
- Is the wobble the cause for the skipping problem? I’m used to seeing wobble in a cassette or freewheel, but this is more than what I’ve had experience with. I’m pretty confident the chain is the right length. My theory is the wobble is causing a microshift of the chain.
- can it be fixed if it is a problem?
