ANDRES P.wrote a review of Absolute Black SRAM Oval Traction Chainring on December 6, 2019
Familiarity: I've used it several times
It forced me to slow down my cadence.
I feel like I get more "output" with less effort so legs and back don't tire out as quickly as before.
I did not have to do any adjustments to my derrailleur, just bolted it on and went on my way. Pretty easy install, the most time consuming thing was cleaning the cranks, pedals and bolts. I was in the area so I figured no sense in installing a new part on dirty bits. No spacers required, I was able to use the existing bolts.
The only negative experience for me is the chainslap. I did not have chainslap before or if I did, it was not audible like it is now.
For $60 something, it's well worth a try.
I plan on a new bike for in the next year or so and will absolutely use a traction ring on it. I don't ever plan on going back to circles.
Furthermore, I had tons of questions and the guys at Competive Cyclist took the time to respond in a helpful manner each time. I would highly recommend this site to anyone that asks. Big Kudos on their customer service.
