Yes encouraging results. My Dura-Ace chain has just arrived to test.
Tehan do you have guidelines for rear mech/ chain set up to get the very best performance from your rings? Perhaps an example picture of the rear mech in the biggest cog of the cassette to try and judge correct chain length? I have mine set according to Shimano instructions but feel the chain is perhaps a touch too long- having said that shortening it made shifting very difficult. Also the clutch is set to be as firm as possible without hindering shifting an I periodically tighten as the mech loses tension over time (especially when new).
EDIT: I have just seen the information on this on your site. Still if you have a picture of a rear mech set up for an 11-36 cassette with the chain on the 36 that would be really helpful. Big/ big plus 2 links still looks a little long to me on my set up but I am not sure.
Perhaps the rear mech set up, chain length set up, chain brand recommended etc could feature on the website so users know how to get the best from the rings? I am just thinking of tips and tricks you might have that the average customer might not be aware of, such as don't use KMC chains... I never would have even considered that!
EDIT: Great to see this added to the website descriptions
Also, FSA's long, hooked tooth ring is not actually Narrow/ Wide as the initial pictures suggested....
