OK, when I bought my 650R, it came with a spare rear wheel...stock hub, big spokes, Excel rim. The spoke nipples weren't right in line with the spokes. Maybe a few degrees off. I figured they built it with a rim that was meant for something else. NOW I'm putting together a new set....stock hubs, big spokes, Excel rims all ordered for the 650R......the same thing is happening. The spoke nipples aren't quite in line with the path the spokes are taking. The front went together perfect....it's the rear. Is this normal? My first thought is that again I have a rim that is just slightly different than what it should be.
