Topic: Chop Hop

If you've taken the sprocket off, was it oversize holes or some thing else?

The sprocket holes are snug fit as is the center hole. It appears the hub itself is not centered and could have been a defect when new but most likely the hub got bumped real hard sometime.
When measured from the axle to each bolt there is a huge difference between two of them.

Update:
I replaced the hub in the rear wheel and laced my rim to it.
Chop hop is gone! No more front end bounce!
The old hub was about 1 mm off center which made a huge difference in chain tension and this transfered to the front as wheel hop. Never ceases to amaze me.
