Yep.

i put them on at christmas, done about 4,000km with them. Shifting was a considerable improvement over the Zipp VumaQuad i had on before, but not as smart as SRAM Red rings.
In terms of the ovalization, they feel different to round rings, but don't know if there's any performance benefit unless i'm mashing my way up a steep climb or sprinting but that's probably a discussion for elsewhere.

hi, which teeth are you using ?I found not too much people using this chainring.
They have only 40T for road bike crank, so is it the same scale of 39T ?thx

I think i've got 53/40. The 40 has 40 teeth so it is not the same as a 39, but i've not really noticed the difference too much.

Well they certainly feel different, whether there is an improvement in performance, i can't be sure. But they are still on my bike...
