Fitbikeco's Crank features a concave design to increase strength and dent resistance, and you can run them left- or right-hand drive. A 19mm spindle is stiff for power transfer but since it's hollowed out the weight stays down. They're available in a couple colors so get a pair to match your bike. And they're strong enough for Van Homan.
