There is not a better solution available. Featuring the lightest hub assembly available, the Qwikchange Pulley System hub weighs in at a slender 5.6 ounces! Made from 15-5 PH (15Cr-5Ni), a martensitic precipitation hardening chromium-nickel stainless steel offering high strength and hardness along with excellent corrosion resistance. 15-5 is used for applications requiring high transverse strength and toughness, such as valve parts, fittings, fasteners, shafts, gears, engine parts, aircraft and nuclear reactor components. The hub comes with 18-8 Stainless Steel screws and ball end hex wrench.

The 6061 T6 aluminum pulley is precision machined to ANSI/RMA dimensional specifications for the best belt grip. The pulleys feature countersunk screw holes for even lighter weight (a 3.4" pulley weighs in at 3.5 ounces). Having the screw holes countersunk also keeps the rotational mass of the screws inside the belt area for better balance. Finally the pulleys are clear anodized for protection and to keep them looking great.
