Rotor System Crank Sets

[landon2]

Has anyone had any experience with the Rotor System crank system that I saw recently? It has a lot
of claims- faster speeds, eliminates the 'dead spot' while pedalling, reduced heart rate, lower
cadences. Sounds too good to be true. I've been to their web site - http://www.rotorbike.com and
read a few reviews, but for the price, it better make coffee in the morning as well as walk the dog.

Hi Guys, I installed (properly adjusted) a Rotor Crank system on my 26/20 Reynolds Weld Lab T-Bone.
All of the claims are true. I increased my cruising speed 2 to 3 MPH (or more) and my top speed
increased about 3 MPH. I can now keep up with the "A" group pace line for the last 10 miles of the
ride on the Jupiter Island, Florida from Coral Cove Park on Saturday mornings.

Hi Again, My experience with the Rotor Crank is that I can't "feel" any difference in the pedal
action except I can increase my cadence rate to the next larger gear on the rear cluster. I am
comfortable at cadences up to 110 - 115+ RPM with the Rotors, where, with my Dura Ace triple, I was
not comfortable at 110 RPM and above. The T-Bone has a natural resonance vibration in the frame at
that cadence with standard cranks. Now I pedal at a higher cadence without the frame resonance.

The non power pedal coming up from bottom dead center travels faster than the power pedal being
pushed down during the power stroke. Since the power pedal is going slower than the non power pedal,
a raise in the cadence brings the power pedal back to speed. Does that make sense?

Well anyway, I go faster...........................

You should post the question on the BROL site. Frank Geyer is a pretty fast guy who races a Jester
and is the US distributer for Rotor cranks. He uses the net name Franknspeed. He's very technical
with training protocol and uses heart rate and watts to rpm ratios, so his data are validated by his
recent 3:53 century!

For anyone whose browser is as confounded as mine by this web site, you can at least get past the
brain damage on the first page with http://www.rotorbike.com/eng/home.htm

I suppose the patents on Houdaille Industries' Bio-Cam have expired by now? (Did I spell that
right?) I recall wanting one, makes me feel kind of old to think that was more than 20 years ago.
Maybe the world is now ready for more moving parts in the crankset.

Marc, two questions ... what's the approximate price of one (I looked at the site and saw no prices)
... and how involved is the adjustment. Thanks, Dave

I read that the price....without installation....is up to $865!

This will have to wait till I hit the lottery.

I just read that they were at a bike fair I attended last month (Bike Motion in Utrecht). I wish I
had known about this then as I could have test ridden the product first hand, so to speak. From what
little I've read about this, it seems a little like the principle used by Nautilus workout
equipment. Interesting. (I'll keep playing the lotto.)
