HEIR Carbon Cranks

The HEIR Carbon Cranks are the most advanced cranks for kids available. Featuring a kid-friendly 145MM length, and constructed of carbon with an alloy 30MM spindle, they are strong, light, and sized right for small riders.

Are these the lightest kid's cranks in the world? Probably, but we can't be 100% sure. Maybe there is someone out there who drilled holes in an aluminum crank until it got light, or filled one of those balloon animal balloons with helium and bent it into the shape of a crank. But we don't want our kids on balloon animal cranks.
