raptor-22 Posted May 11, 2016 Share How popular are oval rings? I see one in 20 or 30bikes at events with an oval ring. How many pros are really using these rings? I don't have quantitative data on that but it also appears to a very small number. If it's as good as is claimed what aren't more pros (road and mtb) using oval rings ?

Bobbo_SA Posted May 11, 2016 Share Funny story - I built up a cracked Litespeed Orion as my IDT bitch. All I had lying around was some oooold 7 speed shimano stuff so I banged it on. I used the bike/trainer combo for 8 months then one day when I was giving it some TLC I noticed the ring was a Biopace. I didn't even notice - after 8 months. Doh! I'm dead keen to give the modern biopace* a go. *yes I know. Oval go to great lengths to say that their rings are way better than biopace. <sarcastic_font> 8 Months and you didn't kill your knees? </sarcastic_font> Link to comment Share on other sites More sharing options...
LOOK695 Posted May 11, 2016 Share Was keen to try the rotor rings, but am having 2nd thoughts now about the durability of them and also about the gear change...... Eldron 1 Link to comment Share on other sites More sharing options...

raptor-22 Posted May 11, 2016 Share No, it's not. I was attributing woo to the concept of elliptical chainrings. IE if it WAS just "woo" (like homeopathy) I think ellipticallicity would fit quite well as a descriptor of the cult. It should be a word, though. OvalityEllipticalcity The word you're looking for is eccentricity I believe And yes I agree elliptical rings are like a cult. No science just cold hard blind belief Glad they work for you. I also find that a significant lowering of my cadence due to taller gearing makes climbing smoother. When the placebo wears off my knees hurt Please don't take this personally. I consider oval rings to be like snake oil Edited May 11, 2016 by raptor-22 Link to comment Share on other sites More sharing options...
Vetseun Posted May 11, 2016 Share 34T Oval. Depending on how oval it is will give you an equivalent of +/- 32T up a climb and +/- a 36T on flat sections.Snap Link to comment Share on other sites More sharing options...

If it's as good as is claimed what aren't more pros (road and mtb) using oval rings ?Roadies I can think of: Julich, Porte, Froome, Wiggins, Millar. Apparently they were used extensively by Caja Rural in 2014/15. The guys who do use them swear by them. Not sure why they arent more popular though.

Captain Fastbastard Mayhem Posted May 11, 2016 Share I have access to a 34t round so I will do a back to back when I can... just so that cadence is retained. raptor-22 1 Link to comment Share on other sites More sharing options...

Froome won it on oval rings last year.Sauser has been riding non-circular rings since 2009 and he is arguably one of the most accomplished mountain bikers of all time. Ariane Kleinhans won this year's Epic on Rotor rings. Why aren't all pro's using them? Might be down to sponsorship constraints or even just personal preference. But oval rings definitely work for me and I can not only feel the difference in my legs, I can see it on my Strava PR's. Plenty of science to back it uphttp://www.noncircularchainring.be/ Edited May 11, 2016 by Ricky G Veebee and Captain Fastbastard Mayhem 2 Link to comment Share on other sites More sharing options...

They might not "work" for everyone but there efficiency cannot be disregarded.

Veebee Posted May 11, 2016 Share More especially when I switched from oval back to round I was faster on round.As mentioned already, we are not all the same so something may not work for you but work for me. We not here to argue about what's best, but rather to find solutions to any problems that may arise. I got my bike back, replaced all cables and had everything set up again, will give it another go tomorrow. bmw1za, raptor-22 and Rick Sanchez 3 Link to comment Share on other sites More sharing options...
