What's your highest cycling speed on flat?
View Full Version : What's your highest cycling speed on flat?
I made 56.1km/h on my walmart 26" 18 speed MTB today, 48 X
17(couldn't shift to 15 for some weird problem), for
probably 10-20 seconds.
After some simple calculation, I figured that I was pedaling
at 160 rpm.
My max speed on a downhill was 53.9 kph. There's a curve in
the hill that slows me down...How do you figue rpm?

^^^^^^^^^^^^^ Arithmetic. Measure your wheel diameter.*
Multiply by pi to get circumference. Divide into 5280
(feet per mile) to get wheel RPM. Divide by your gear
ratio (chainring teeth/cog teeth.
*Get this in feet. Measure in inches and divide by 12, or cm
and divide by
30.48)
I think it would be a lot easier to get a computer with
cadence to monitor my rpm while riding.

Skipping the derivation this time, MPH times 336, divided by
wheel diameter in inches, times number of cog teeth, divided
by number of chainring teeth

Assuming that's not a troll, that's darned near amazing. I'm
really happy breaking 50 km/h in a sprint on my fast bike,
though I did manage 55 yesterday.
Time to start racing,

I believe in Arnie Baker's book "Smart Cycling" he mentions
that some track racers get up to 250 RPM, and lists 160-165
RPM as an achievable goal after two years of speed work.
I've managed 140-145 RPM on my wind trainer doing one of
Baker's workouts, but I've never really spent much time on
leg speed.
My highest speed on a flat - that I remember - was only
about 32 MPH (~52 kph) on my mountain bike, huffing to make
a green light. The road is really more of a false flat
(slightly downhill in the direction I was going).

Several times I've gotten well into the 40s (mph) on the
flats, each time while drafting a dump truck. ;-)
As I recall I was pretty much spun out in 52/12.

Get a computer that measures it for you, or go to
http://www.sheldonbrown.com/gears and put in your info. You
can then see charts of mph or kph at various RPMs. Find
your speed at the same gear combination as you were in, and
see your RPM.

Why achieve that goal? Planning to compete in a cadence
competition?

I quit drafting dump trucks after I tucked in behind one
towing a pup.

I drafted a truck down a hill at 60mph, and followed him for
another mile on the flats at the same speed.
In a 52-13 that's about 180 rpm.

Sort of. He wasn't in his 52-13, he was on the small
chainring. ;-)

Right. Sort of made a hamster look like it's on Valium, eh?

I think Arnie was addressing this advice to track racers. I
believe track bikes have only one gear, so in a way it
really is a "cadence competition".
Sprinters might also want to hit a high cadence.

OIC. That makes more sense.
The other day, I decided to see what kind of cadence I could
hit while still producing power, and was utterly shocked to
pedal 150 rpm and continue to accelerate. It's not something
I'd want to do, and I'm pretty sure I produce more power at
lower rpm, but my legs went that fast, and reasonably
smoothly too.

By which you mean what? And were there dire
consequences for you?

One meaning of pup is the trailer that they put behind
utility trucks and such. Guess there is no reason you can't
have one behind a dump truck.
They can surprise, because they are narrower and tucked in
behind the truck's silhouette.

The worst, IMNSHO, is a "lawn mower truck!"
You know the p/u with a trailer wider than the truck with
the mowers handlebars sticking over the side at about a
riders head level?
