Question on Stages please: I have a Dura Ace 7900 BB, and then a Shimano compact crankset (not entirely sure what R something?, could find out if important).
If I went with Stages is the Shimano 105 compatible? Or only the more expensive Dura Ace 7900? Or neither. There's virtually no weight saving between the two.
