# 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've only done this once and that was 38.3 mph (I was riding in
traffic and needed to go very fast). I can maintain 36 mph for several
hundred feet. I've done this in front of a police car once or twice so
I could make a legal left (US).

At 38+ mph I'm at about 120 rpm for a 53x12 & 700C. I can do up to 182
but it's really difficult to stay seated at that point. I really need
to put more work into spinning but I've been spending a lot of time
working on climbing. I live in the flat lands so it's difficult.

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.

Wasn't that in a movie?

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?
