Skyway doesn't, and will never make Tuff Wheels in 26" or larger sizes. The best you can do is build up a 24" bmx and rock some
colored tuffs. <-- The guy who runs that site works for Skyway. I recall someone asking him on a bmx forum if 26" tuffs are a possibility. Apparently Dupont ZYTEL Nylon, the material tuffs are made out of, would flex WAY too much for them to be considered a safe product. Hell, people even complain about 24" tuffs flexing too much.
They look bad-***** though.
