Gearing

Chainring ÷ rear sprocket

Lower ratios provide more mechanical advantage for climbing. Higher ratios turn the rear wheel farther with each crank revolution.

RPM
Theoretical speed from published tire dimensions; see the evidence note below.
Published build46T · 17T
Ratio2.71:1
Estimated speed Gear19.3 mph

Estimate uses the published front tire 700×28 (series unverified) as a proxy, corroborated by the wheel size. Rear tire size is not published or verified. Approximate circumference; actual rollout varies with tire and pressure. Theoretical, not a maximum achievable speed.
