I picked up and inspected a set of the new Skymaster gear and wheels this past weekend at Superman, and I must say that they are really a cut above the older version. The wheels are substanstially lighter and are now inflatable allowing you to adjust the amount of air you want in the tires. The retract mechanisms are really smooth and well finished, with strong appearing trunions blocks and linkages. As Morne said these are defintely a higher quality product, at least the ones that Eric was displaying at Superman.
