Anyone use these things?
Also, I am really sweating a racing/training wheelset, around 1500 Gms for under $500. I have narrowed it to
1) Easton 90 SLX
2) Rol Volant
3) Williams System 19
I don't really need a new wheelset, but I have been having this horrendous and truly time consuming urge to get one.
I hate being OCD.

I use 'em on my MTB. Can't say I notice a HUGE difference. But maybe. CCC swears by 'em. So do a few others. I'd like to try them out on my road bike some day.
Some day...
i think it might be hard to maximize the benefit unless you put them on every bike and give yourself enough training time.
ask bobby j if he still likes them. maybe he just gets paid a lot to use them.
my big power related upgrade will be powercranks...someday.
Nice, I wish I could find some scientific research on them. Would it not be reasonable to put this setup on a powermeter and measure the produced wattage versus the expended wattage and compare that to a normal chainring?
one word:
Biopace.
There's a reason the great and mighty Shimano ditched them. Heck the final versions weren't that much different than those rings.
Power cranks BWAHAHAHAH.
sorry - search up BSNYC for a good powercrank crack.
(fine i did it for ya)

"And if his spirit is not yet broken completely, or if he doesn't quite trust himself, he might even be riding a pair of Power Cranks, the cycling equivalent of a Victorian anti-masturbation device."
The only way to check power is to have the same # teeth chainrings on the same crank and were able to switch back and forth under the same RPE load or same speed & cadence and watch power, or same power & cadence and watch power. valid comparisons are impossible to find. Individual power outputs vary too much.
Heck i would wager the average RBR reader would easily be able to sustain an extra 100 watts beyond what they thought if they were out on a group ride with Roubaix Girl.
Save your wheel cash and fly to Europe and race ;) THAT will make you way faster than having cool ass wheels.
I rode the BioSpace cranks on my neon green Marin for about a year. Man those were the days. Yeah, I am thinking about maybe holding off on the wheelsets and investing in stocks instead. Damn, Countrywide Stocks just dropped 28% today and maybe I should be getting back into the market and buying against these companies to make some $$$$.
Sorry 28% loss for the year and 19% TODAY...
If those rings were really working at increasing watts don't you think that competitors, such as your fellow Japanese component makers, would be marketing them? Shimano surely still holds a patent on eliptical chainrings from Biopace days, so patent infringement wouldn't be an issue.
Power Cranks on the other hand...
You should buy some wheels so that you can stop thinking about them and find something else to obsess over.

Actually, patents only last ten years, and those rings were patented maybe in the early 90's so that would explain the resurgence of new variations on older systems such as this.
According to my friend at the patent office, the protection is only for 14 years for design applications.
Lookie lookie Yash! See what I found on ebay! Rotor Q Rings!

Why do I feel like a drug pusher?
They shall be mine.
Mike there are no posts on your blog. I think you need to post pictures from last years season.
You're right, I do need to add some pics. Since there no cross I should have the time to get some stuff up this weekend.
