How fast can you pedal?

[Bluey_27]

Well?
i can pedal about 170rpm with 175mm cranks. Does crank size make a difference?

yeh, the longer the crank the easier it is to turn but you have to move more.

 

[topcat]

I've pedalled 240rpm on an SRM equiped stationary bike

Shorter the better for high cadence. On the road 88kph in a 39x13 which is 225 give or take.

 

[Bluey_27]

wow, 225! What kind of leg speed workouts do u do?

I started track a month or two ago. I can really feel my pedal stroke getting better, but I have to work on my track sprints (leg speed in particular)

Just motorpacing and occasionally downhill sprints on my track bike. I'm certain that I've gone a lot faster on the ergo and doing the downhill track bike work but have no way to back it up.

I have done about 185 on my cyclocross bike on the lowest gear ratio of 42-32, looked pretty silly and wasn't quite smooth...

Sorry to but in on a dead post, but it seems that optimal crank length seems to be a function of lever length, shin and thigh lenth as well. I am not an expert on the subject, but the shorter the better is not always the best. BTW 84kph is either down a big hill, or that poster is a member of an elite nats team being pulled by a motorcycle.

 

[velodrome.co.nr]

i once went 62mph down hill
my average cadence on normal rides is around 108rpm

Your insane Most of the experienced track guys are telling me to do overspeed work in the 170-180 range. I am not sure if there is a practical purpose fore more than that. Seems that the top speed of the fastest in the world....no drafting or hill is about 45 mph.(73kph) 50 mph with a motorcycle. Hey I could be wrong too. My fatest on a flat is 39 mph 48x15 155 rpm. I stored it on powertap

 

[PartisanRanger]

I dunno, fast? My style focuses more on the bigger gears and more power per stroke.

While riding on a 39x12 I've done 300rpm give or take 10rpm for about 10 seconds on a stationary bike with zero resistance but my heart rate went from like 50% to 95% so I had to slow down. I was literally taking off... ;-)

 

[redbacks]

I don't know much about gear ratio's and stuff but i was on a mates road bike a few days ago, he has a candence mode on his cycle computer on a flat i had reached a max rpm of 176. i wasn't in a top gear or anything 16speed i was probably in about 10th. the fastest i have ever gone was in a track sprint against the same mate and my coach who incidently is my mates brother. He was ranked 8th in australia in 200m sprint he did something like 12secs. anyways i lost the race but hit 59km/h they marked about 62km/h. it was a 4 lap scratch.

 

[IEatRice4Dinner]

i did a spin of a little over 220 with 172.5 arms... (im 5ft 5 and should be on smaller crank arms)

I can hit 198 on my road bike in my smallest gear. I never tried a stationary bike. I did it on my trainer and only got a bit higher. To 204. It felt like my chain was going to snap.



There’s a lot o variations with in leg speeds. One will be super high but that’s because he is on one of those stationary bikes.
