Absoluteblack Oval Narrow/wide Ring

Anyone tried one of these? Thoughts? Any improvement in pedalstroke feel/lack of fatigue? Even if just a more-or-less perceived one?

My better half uses Oval Concepts rings on his two mtbs and commuter. He reckons they are awesome and you can feel the difference, enough of a difference to change all bikes!

We have looked pretty closely at it, there is two issues, 1, it's fixed position so you can't tune it to your pedal stroke, and 2, we see quite uneven wear on chain rings from left and right pedal strokes not being even so you are not getting the full effect of the claims, which means you are essentially riding a round ring anyway.

Personally I think it's a solution looking for a problem.

Looks worth a try. There are a number of top level road riders on oval rings so there may be something to it.

Shimano definitely stuffed it all up with Biopace back in the day and so a bunch of people are probably pretty wary of going oval after a biopace experience... but apparently the biopace elipse was in the wrong place on the rotation of the cranks?

Yeah all oval rings now are the opposite to Biopace

If you made narrow wide oval rings in say a 40 tooth someone would be very happy. Just saying....

most of the rotor stuff has multiple chainring holes so you can tune the rotation of the ring to how you pedal which makes much more sense than the single mounting option of the other brands.
