Help needed from the mathematically inclined, please.
Fixed gear, 48x18 on 700c wheels, speed attained was 56.7kmh.
Can anyone tell me what cadence that equates to?

Cadence and speed calculationHelp needed from the mathematically inclined, please.
Fixed gear, 48x18 on 700c wheels, speed attained was 56.7kmh. Can anyone tell me what cadence that equates to?
Re: Cadence and speed calculation2.1m (approx. 700c rollout) x 48/18 = 5.6m per 'rev'
56,700 metres/hour = 945 m/minute 945/5.6 = 169 rpm.
Re: Cadence and speed calculation
I'll post you link when I get home that has it all covered.
Re: Cadence and speed calculationthanks, hmmm 169rpm seems much higher over sustained effort. Thought I was nearer the 200.
I was over 55kmh for quite some time, maybe 250m, going down the hill north from the Morialta Falls main gates past the Black Hill Conservation Park, on the fixed, of course, Saturday morning.
