Best New Product...gotta Try It!

Notices
Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

Best New Product...gotta Try It!

The product is the RotorCrank...costs $700-800, adds 1 lb. to your bike, has noticably more friction than your existing crank....sounds like a poor testimonial....huh? I rode it for 2.5hrs. and I bought 1 and will soon be buying another. The best comparison I can think of is when I changed from old , straight, snow skis to a ski with a parabolic cut. I thought I had just completed a year of training by the amount of improvement it made. Almost the same with the RotorCrank.
First off let me say I can't wait to hear from all you closed-minded, traditionalist, weight weenies. And Laggard ...I think I found another good controversial topic. I am sure that I will get lots of fun comments from those who haven't tried a RotorCrank. They will tell me about Power Cranks, and why aren't the pros using them...yada yada yada.
This product is the real deal...I believe that Leonard Zinn nominated it "Best of Show" at inter-bike in 2002. Is there anyone else out there who has tried it...let me know.
Look up a web site as I'm too computer illiterate to post a link. Call Howie Cohen and give it a try, I guarantee you will thank me for the referral. The product eliminates the dead spot in your pedaling stroke...I know, I know, just learn how to spin....right? I actually have a pretty good spin, and now it has power too. I now believe I am a faster rider and I know I am smoother and will increase the distance of my rides due to the increased efficiency and comfort. After my club ride next week will know how much faster. Lets get some comments here. I don't work for the company, don't make any $ from the product, but I bet that within 4-8 years 50-70% of you will be riding a version of it...any takers?

Just like 4-8 years after the arrival of Biopace, we were all riding that, right? Oh thats right...

I'd like to try them on my singlespeed as I'm curious, but boy, is that one hell of a testimonial. You should set up a church or something.

you want more pedaling resistance? get yourself an over-tightened loose-ball bottom bracket.

More pedal resistance... I'm not the brightest person in the world but when I want more resistance, I click the little lever behind the big lever in my right hand once, twice for more resistance. Or I steer the bike to a place where the ground in front of me is one small increment higher in altitude than the ground behind me.

Isn't the rotorcrank the one with the cam-lever action or something? I think they have a ultra-lightweight version that some pros are using. I have heard it takes getting used to but after you adjust, there is significant improvement in TT's and such.

I wonder if there will be some at the TDF this year...

Never ridden them so I don't have an opinion either way. Just like Seely said, there is a "next greatest" thing every year or two so I guess if they can get pros to believe in it, they might have a chance.

And this isn't the same concept as Powercam cranks? I have ridden with a few guys that use rotorcranks, two of them have had the cam mechanism screw up and leave the crank arms loose and completely useless. I'll stick to what is known and doesn't cost (and weigh) a ton.

its looks to me a bit like voodoo.. when I will see Lance Armstrong and other use it on TdF, Ill give it a try.. If any one is interested in optimizing every little ounce of power, it would be those guys...

Here what it looks like:

Isn't that just a weight to add some rotational momentum to the crank?

I saw Cadel Evans training in Melbourne over Christmas using some weird lookin' cranks. He told a friend of mine it had something to do with independent resistance -- but I dunno. Could just be a training aid.

those are the powercranks. each crankarm spins independently, so you have to have an even pedal stroke, it forces you to pull up on the upstroke. its kinda like doing one-legged drills, only you are doing both of your legs at once. theres a thing on them on pezcycling news

I think the rotors are kind of a bad idea. they effectivly ruin your pedal stroke, becuase they eliminate the dead spot, so you dont have to apply power through the whole spin. when you go back to regular cranks your stroke will be way off.

I wonder if the UCI has banned them yet? I remeber reading something about how all new technology must first be approved by them before it can be used. thus why camlebacks aren't used, diamond-frame bikes are required, etc. this definitly bannable.

It still amazes me that they permitted aero bars. Maybe it was the dramatic way in which LeMond won using them in '89, with his accident and all. Perhaps they didn't want to rain on his parade in any way.

Imagine if the UCI ran golf, they'd fix up the equipment controversy in 5 mins.

As I suspected...about an 80% negative reaction, mostly by those who don't even know what it is. The human being is ultimately one of the most adaptable species in our world yet most are unwilling to think outside the accepted norms....splain that to me??? While coonsidering the advantages of Bio-pace Seely perhaps you could include a history of the clipless pedal...or perhaps gears on your bike...who would ever make a saddle with a hole in it...a solid wheel that weighs almost twice a conventional wheel???? geeeesh! Carbon fibre cloth used in a hub??? why can't we all just ride a single speed and stop trying to screw things up? huh?
Thylacine...now there is a thinking,yet skeptical person. Someone you can talk rationally to. So here you go Thy. Call Howie at RotorCrank, purchase a set for single speed...he will guarantee refund if not satisfied, honestly. I'll pay you $100 if you don't keep them. Installation is a little more than a typical crank and must be done correctly or they come loose as mentioned. If that happens you go from "best thing ever" to "Morons wouldn't ride these". Thylacine...with you're experience, just try it, you won't regret it.
UCI accepted them and a Div. 2 rider sprinted to 10th place behind winner Armstrong earlier this year.
Remember that Shimano pays Postal something like 1.25 mil. plus 200 gruppos....what would you ride??? and thats just Postal.
slovoid....you just keep shifting up while climbing hills and I'm sure you will be in front at the top.....right? Perhaps you should just shed the xtra 2lbs.,go single speed, save the $250-400 and go faster. Let's see...less money, less weight, work harder....geeesh thats it... nirvana, why did it take so long??? it all adds up. hehe

Oh, by the way Thylacine...I listened to you and didn't purchase an over-priced factory wheel set...I am having some built for $200-300 savings....because you were right and it made sense.

Reminds me of telemarketers trying to sell me stuff, usually I'm having dinner, and won't hang up the phone. No, no, it reminds me of infomercials at 2am.

What a waste of money ! Want to develop power ?

Do steep HILLS (50 reps with less than a minute rest) period! The one I have near home is almost 40 degrees and 3 block long. I always laugh at those tecno devices that all they do is make somebody's rich at the expense of people's naiveness and curiosity.

Perhaps I should add a gas motor to my bike. If adding 2 pounds with your device can make me a little faster, adding 10 pounds with MY device can make me 50-60% faster, in fact, I can cruise at 50mph and climb hills at well over 30.
I'm not saying that it doesn't work, there's always a better cheaper way.

Ok I looked at Sorebutt's picture - thanks. I did an internet search. I still don't understand what it is yo'all are talking about. I guess it doesn't matter since I'm not likely to spen $800 for it.

Rotorcranks... are designed so the cranks never have pedaling deadspots. Essentially the cranks move and realign at the deadspots so both cranks are constantly at an angle where the legs can apply power... look at the geometry - the cranks aren't lined up in certain angles.

Powercranks - just two cranks that function independently, the idea being you have to train your legs to pedal independently.

58,8?? Isn't that a little hard on the knees? Or are you cycling with the same force as say a 53?

Corsaire...what about those techno devises that were laughed at that you can't do without???? Do you ride clipless?? They were marketed for 2-4 yrs. before Hinault became the only pro rider to use them in 83 or 84.

I suppose you don't have one of those new fangled shifter things either???

You still riding tubulars...even when training?

Of course ...steel is real...you must have a bike that weighs???? 26-30 lbs ? Can't weld that dang titanium crap you know???

Aluminum wheels..hell no it's just lead for you

It's the 80/20 theory...20% of the population keeps progress going forward until even the most un-imaginative begins to accept change....then that change becomes the norm and they fight for it as if they were the inventor...forgetting they slammed it.

Who needs one of them danged gone computer thingies anyway

Sorry gotta go out to the Outhouse and take a poop...no running water here ya know!

And slvoid....like I said...when you begin to ride exclusively on a single speed or actually try the thing then you get some credibility.....until then, just an uneducated negative attitude...we should all strive to learn before making decisions...sorry but it's true. Open your mind and experience things...try sushi, meditate, race a car, study fuel cells, ride a carbon bike....or two, maybe a bong load'l help ya...hehe
