I bought this to use with a Rotor 3D crank on my Cervelo S5 VWD, but it also works well with an older five-arm FSA crankset I have too. You can feel less resistance in the dead spots during each rotation and it has been easier to keep a higher cadence. I would definitely recommend this to anyone looking to get some increased performance out of a new chainring.
In my personal experience, it took me far more than ten hours to get use to the oval rings. I’ve noticed that, in my case, on lower cadences they are leg killers, but on higher cadences they definitely add some marginal gains.
