53×11 ratio 4.818 — 10.142 m per stroke
A 53-tooth chainring with a 11-tooth sprocket gives a ratio of 4.818. One pedal stroke carries you 10.142 m, and at 90 rpm that is 54.8 km/h.
Speed
Speed is the ratio multiplied by cadence. Grinding a big gear slowly and spinning a small one quickly give the same speed, but legs last far longer doing the second — which is why most riders pick the gear that keeps them near 80 to 90 revolutions a minute.

Worth knowing
- The ratio is the chainring divided by the sprocket — bigger means harder and further.
- Two combinations with the same ratio are the same gear, whatever the tooth counts.
- Speed is ratio times cadence, so neither number settles it alone.
- These figures assume 700×25C wheels with a 2,105 mm circumference.
Common questions
Q. What is the ratio of 53×11?
4.818. One pedal stroke carries you 10.142 m, which is 126.7 gear inches.
Q. How fast is this gear?
At 90 rpm it works out to 54.8 km/h. Speed scales with cadence, so 60 rpm gives two thirds of that and 100 rpm a little more.
Q. Is there another combination that feels the same?
No other combination in this table sits within 1 % of this ratio.
Q. What happens one sprocket lighter?
You land on 53×12: the pedals ease off, but each stroke carries you less far.
