I'm partial to the Zero Drag Racing (84a) wheels from RollerBob http://www.rollerbob.com/cat-10.html
The 86a version wears a lot longer but is a harsh ride and is slower.
Post by Nomen Nescio I am looking for new 80mm wheels for my RB Twisters. Looking for something with good grip and wear for asphalt and concrete. Any ideas? Greg
