HEIR Crank

My son's bike finally has cranks that fit his short legs, and the difference on climbs is night and day. They're cold forged so they feel stiff when he stomps on the pedals, but they're light enough that he's not dragging extra weight around. Install was straightforward with the direct mount setup.

The cold forged crank is noticeably stiffer than the alloy ones I've used before, yet it's still light enough for my daughter to handle on climbs. The shorter length option fits her perfectly.
