They went in great!! Fit perfectly and they feel so nice when gliding down the road. Super smooth, zero resistance I also like that they're red.

2695 Lake George RdOverview
The Nachi 6004 -2NSE9C3 pairs a 20 mm bore with a 42 mm outside diameter and 12 mm width. Rubber contact seals ride on the inner ring land at both sides, giving a far tighter barrier against water, dust and washdown than a shield can manage, at the cost of a little more running torque. The grease is sealed in for the life of the bearing. C3 clearance offsets the fit-up and thermal losses that would otherwise leave the bearing preloaded, the cage is sheet steel, and the assembly is rated from -20 to +130 degrees C. Well suited to dirty or damp duty where relubrication is impractical.
