Thank you for the inter...yes I have read all of it! Thank you for the interesting article! <br />I have done lots of road cycling and mountain biking in the 80's and 90's and have used biopace rings until last year when my last set, fitted to a mountain bike converted in city bike, was stolen together with the whole bike.<br />My impression is that oval rings work well as long as your riding position is always the same. When going from seating to standing the whole mechanics of pedalling changes. If the position of the rings was optimized for seated riding, they would not work well when standing. Hence their success with recumbent where you do not change position.<br />As a cyclo-tourer, I have always prefered to pedal seated all the time, and I was frustrated for not fining small enough chainrings, and big enough rear sprockets, to do this before mountain bikes took off.<br />Now that I am older and I cycle just to keep myself fit and to get to work happy, I find that I prefer to stand up and "dance" on the pedals, so I have given up my search for big sprockets.<br />I am doing the opposite path to professional riders, who 40 years ago used to push big gears standing on the pedals, and prefer to spin light gears now, remaining seated even on the toughest hills. But I have always been rather unconventional. Anonymoushttps://www.blogger.com/profile/02646801768570999907noreply@blogger.com
