What are your thoughts on rear bearing size?
1.25 x 2.440 OD vs 1.25 x 2.835
No so much about price, the cassetts are the same price, the larger cermaic bearings are about x5 on the price and the steel bearings are about x3.
I see an advantage in the cassettes for the small bearing because there is a lot more material there (stronger?)
My question is will the larger bearing spin more freely and last longer (faster and more dependable)?

Honestly Curt, I would want as big a bearing as I could get. A larger bearing handles more load, turns slower and runs cooler.
