3/32 x 13/16 Drilled Big Full Hub Piranha Treated Alpha has a proprietary process of chemically treating the rubber to alter it's characteristics. The treated Piranha rubber is a bit firmer, and has a bit less grip. But it also is longer wearing and because it has less rolling resistance, is faster on the straight-aways and in the bankings. Try it if the regular Piranhas seem a bit too soft and grippy. These tires are for those of you like the "euro" style hubs. Drilled for less weight and better acceleration. Drilling the 18 holes in the rims, removes about .2 grams per pair. These are plenty strong enough to race with. Lighter is better!
