<p>If you are interested in anything let me know. Make me an offer.</p> Rotor Q Rings verses Biopace for CXtag:cowbell.cxmagazine.com,2013-05-26:1198434:Topic:1428722013-05-26T03:06:53.763ZBrokenmanhttps://cowbell.cxmagazine.com/profile/Brokenman
<p>I just made an interesting observation about rotor rings and the old biopace and I was wondering if anyone else had similar experiences. Bottom line, as much as Rotors are touted as the new great, expensive thing, they are really identical to biopace. </p>

<p>I have been riding Rotor Q rings for about a year now and logged a few thousand miles with them on my road bike. Although I do not find them “smooth” as others claim, they have all but eliminated my knee pain. So now I am looking to set up my CX rig with the Rotor Q ring single front setup (I am also somewhat admittedly influenced by Vos after watching her decimate the Worlds field with these rings).</p>
<p> </p>
<p>A fiend of mine told me to just install my old biopace rings. He contended they are oval and therefore the same. A quick internet search indicates that this is not true and that the biopace rings are actually the opposite as the Rotor rings are designed to decrease the effective chain ring size when your pedals are in the non-power section of your pedal stroke (roughly at 12 and 6 o'clock) in order to help you speed through that part and apply power where it counts, while Biopace rings <i>increase</i> effective chain ring size when the pedals are in the "dead" zone of your pedal stroke. </p>
<p> </p>
<p>To prove to my friend that I was right, I decided to compare them side-by-side. I have 42T version of both so I just lined them up. I was amazed. They really are identical. If you rotate the biopace counterclockwise 2/5’s (or two bolts holes to the left) then it is the same as the Rotor ring when in the 5 position. Both the overall shape and teeth line up to a millimeter. </p>
<p> </p>
<p>I was wondering if anyone else has tried using the old biopace as a substitute for Rotors?</p>
