3/32x.790 Drilled Big Hub Piranha Treated. Drilling the 18 holes in the rims, removes about .2 grams per pair. These are plenty strong enough to race with. Lighter is better! "Soft, Natural, Aromatic Rubber." Alpha's Piranha tires really bite the track, especially when very clean and/or slippery. And they feature high quality, lightweight magnesium rims. These rims give the Piranha tires a big advantage over the other brands using aluminum hubs. The original Piranhas have won thousands of races! Features a cup point set screw. Color: Black only. The big hub Piranhas have a set screw boss area like the original Piranha tires, but have a larger diameter rim. This results in a lower rolling resistance for greater straightaway speed and less sidewall deflection, resulting in faster speeds on banking.
