Another new wheel with the same Revision flex hub, so we are expecting a very durable product, made in the USA. *The image and wheels shows 74a on the label but they are in fact 84a. This is a mis-print*. Superb grip, speed and durability on rough outdoor surfaces. Extremely long lasting urethane. Standard 608 hub to fit standard bearings. Includes a set of 4 80mm 84A Wheels.
