Thanks, but I used a quick link and have repeatedly checked the chain for tight links but there are none. I’m really at a loss and am wondering if the new freewheel might be defective. When I put the 32-13 freewheel back in the skipping stops. I’m also wondering if an 11 tooth 7th might be too small, but other XPremium owners have used a 34-11 without issue.
