Hi all,
Hoping one of you highly knowledgeable cyclists can shed some light on something for me. I'm just wondering if a Dura Ace 7700 crankset (9 Speed) will work with a Dura Ace 7800 groupset (10 Speed)? Would it work out the box or would I have to change the chainrings? Or would it not work at all?
Thanks in advanced.
