SHORT CRANKSET SELECTOR GUIDE
Start by choosing your watts band, then look at various crank lengths to the left of the chart. The chart will highlight where the two meet, showing the seat-height range (measured in centimeters from the bottom bracket to the top of the saddle). If you’re between sizes, a shorter crank usually feels more natural, opening your hips and helping your cadence stay smooth. Keep in mind that terrain, flexibility, and riding style can also influence the best fit.
