Just ordered a set of the new OCP rings to try on my training bike. Will report back when they arrive.

After 2 rides on my doval chain rings. I think they maybe more flexy than the normal no q rotor chain rings.

Can't say I've noticed them being particularly flexy. Also can't say that I really notice any difference pedalling the things, though. Have been riding them on my training bike for the last 10 days, but will also try them out for a 25 I'm doing next weekend. I'll see how I feel after that.

took a great effort to readjust my fd, turns out that it has to be angled out more to aid shifting to the big ring. However shifting is only 75% as good as round sram force rings. too early to comment about the effectiveness of these rings yet

Agree on the shifting. I've been doing my own wrenching since my junior MTB days (nearly 20 years), and I can't get the front set up to reliably shift without overshifting.

Quick update. Swapped them on to my race bike yesterday and did a 25mile TT this morning.

The shifting problems I had on my training bike are gone with the 7900 setup. I'm thinking I may have slightly bent the Apex front mech on the other bike. Shifting with Dura-Ace is spot on.

EDIT: Not that I shifted out of the big ring during the TT. ;)

I am going to give them a try but will get the 360 version. Now using qrings and want to try something more extreme

But how do you find them? When racing TT.

Just fitted my set, got them at a steal of a price going through their Korean site and their 99p start eBay listing :D
Took them out for a test run today and they felt like my pedal stroke was a bit smoother, although the acceleration seems a little late but they are in one of the middle setting at the moment, so I will change them and report back!
