Was doing some research for my new road bike i'm planning to build which I would like to have 46/36 gearing on (I don't grind gears, I spin them
). Came across the stronglight chainrings that are in engineered to the profile of the 7950 crank.http://www.xxcycle.com/110-type-dura-ace-ct-10-speed-outer,,en.php
Note, I haven't bought these, so I have no idea of product quality nor actual availability, and i've only used xxcycle once before (years ago). Also, I couldn't find the specific 46t chainring on other sites which have these specific stronglight chainrings. But, seems ideal for what your asking
btw, i'm currently looking at going down the route of a 2012 red crankset with praxis 46/36 cross rings, but as indicated on their website the 46 ring unavailable atm.
It's probably close to 100grams lighter than the dura ace/stronglight combo.
