Gary do you know of any non aneccdotal sources where I can look at the often discussed benefits to these ? I’m interested in a set for my biking ass but I want to see some evidence before I’d consider it.
Currently, we have tests showing metabolic improvements and lowered lactic acid production, lower heart rate and lactic acid production riding at the same speed, preliminary increases in wattage, and the preservation of knee health.
We also have hundreds of anecdotal reviews, comments, emails, reports claiming improved performance.
We are working with researchers to provide performance/wattage based test results, however this is a slow process as you can imagine.
If you want, you can send an email directly to the invento for more infomation at info@rotorbike.com
With the 30 day performance guarantee (full refund within 30 days if it does not work for you), it seems like a no brainer to at least try them, if they are in your budget.
…you’re gonna waste a lot of time reading…just get them…they’re the bollocks!!! I have them on my two bikes…my Orbea Orca and my Trek Equinox 11
I’m not sure if it’s of any interest to you, but I feel confident in technologies that replicate nature. Maybe I’ll change my mind on this someday after having had further insight, or maybe not, time will tell.
As the sun approaches it’s peak altitude, relative to the observer, it effectively slows down. Meaning, just after sunrise and before sunset, the sun is moving through the sky much faster than it does at high noon. I think that is significant when trying to understand the utility of Rotorcranks, given that insolation values at a specific locale reach their peak when the sun is at it’s zenith (as perpendicular to the ground at that locale as the sun will get), just as power output levels reach their peak when the force on the cranks are perpendiuclar to the ground.
You can find altitude/azimuth tables here http://aa.usno.navy.mil/data/docs/AltAz.html
Insolation - Amount of solar energy reaching a surface per unit of time.
Altitude - The vertical angular distance of a point in the sky above the horizon. Altitude is measured positively from the horizon to the zenith, from 0 to 90 degrees.
