Hi all,
I'm currently in the middle of a build. I have a some knowledge when it comes to bike building but I'm no pro and I'm just a little confused about something and would be very grateful if someone could help out.
I've got half a 9 speed DA 7700 group (BB, crank, front & rear mech and STI levers) which is all ok but this is where it gets complicated. I have a DA WH-7800 wheelset which is 10 speed. What is the best way to configure this? Will putting a 10 speed 7800 cassette + chain work with the 7700 group or do I have to get a 9 speed 7700 cassette + chain with a spacer? Or will neither work?
Any help would be appreciated.
Thanks
