I like using rubber sheilded bearings from Avid RC. Good prices and good bearings.

Asphalt or Carpet? Asphalt I would think dirt is still a problem. If you want the best you could go with Ceramic by Acer but they are $100 for a full set.

Default Man don't get the Acer bearings.

The seals fall out. I would spend the little extra money and get the yellow sealed ceramic bearings for your drivetrain. I have the green sealed ones in my wheel hubs and they are lasting much much longer than any other standard bearing I have used. I'm sure the ceramics are the bomb.

Metal shields on asphalt work fine.

this is from their site

Lightweight ceramic balls dramatically decrease the centrifugal force placed by the balls on the rings. This, in addition to a 50% higher modulus of elasticity than conventional bearings, and Grade 5 smoothness of the balls (contrary to popular belief the lower the Grade number a ball is, the rounder and smoother it is), produce a lower coefficient of friction at the ball-raceway interface, leading to over 33% less friction in the bearing as compared to conventional bearings, and far less wear, lasting an average of ten times longer than conventional bearings. Sealed with our exclusive no contact seals for the lowest friction and best dirt resistance. These are the best and most high tech seals available.
