[python] Re: Elliptical chainring

Hi Daryl and listies,

rotor also manufactures some kind of unround rings. They call them Q-rings.

for those of you, who, like me, don't do spanish, go to the page Daryl mentions 
below, click on the little red Englis button and well keep clicking. The color 
choices for the website make reading a bit pinched...

interesting products,

ron
