>From the Japan Handmade Bicycle Show :

Can someone identify this _aluminum_ stronglight 49D chainring on a TOEI? The 5 bolts connect to a ring with 3 main spider arms, each arm branches right away into 2 parts, creating 6 arms at the outside edge, which like a Stronglight 57 or a campy 42T NR - has very thin slots all along the outside edge. I am reminded of a Renee' Herse chainring with straightened web. For a picture (won't last), see this :
