Rear wheel compatability
I am looking at buying a used OP/DA wheelset for my road bike. The rear wheel is currently set up with a 10 speed cassette, but I have an older 9 speed dura ace group (7800?) on my bike.
Can I simply replace the 10 speed cassette with my 9 speed cassette? Do I need some sort of spacer? Or is this just not possible?
Thanks!

7700 is 9-speed, 7800 is 10-speed.
You can't put any 9-speed cassette on a 7800 hub.
You can put 10-speed cassettes on 9-speed hubs though and it's possible your seller did this.
Answer is: it depends. Need more data.
