Gear inches, rollout, and cadence
上坡前先知道齿比。
Gear turns a chainring, a cog, and a wheel into gear inches, meters of rollout, and speed at your cadence. The tallest gear is free. $5 unlocks the chart. $15 keeps later bikes. Nothing renews.

问题
Gear 是根据你填的轮组和齿数做的滚动距离表。胎压、风和磨损的飞轮会改变真实速度。它不是fitting，也不量车架。
