Wow they are expensive. Has anyone fitted the Dura Ace 7900 outer ring to an R603 crank? They are too expensive for me to buy and find it doesn't work.
I've read through the other threads linked and find people talking about this but I can't recall anyone who has done it and posted the results.
The Davinci cranks are looking better by the minute.
