All my cogs and wheels are the yestertech 9 speed variety. If I buy new wheels obviously the hub will be 10 speed. Will my 9 speed cogs work?
The difference in the cogs between 9 and 10 speed shimano is the depth of the splines. 10 speed cogs can fit on 9 speed hubs and 10 speed hubs, however 9 speed cogs cannot fit 10 speed specific hubs. The Dura Ace hub is only ten speed specific, with taller splines on the freehub body. Most aftermarket hubs are 9 and 10 speed compatabile for Shimano, now. So it depends upon which wheels and which hubs.
Shimano is the only company out there making a 10 speed specific hub. As long as you don’t buy Shimano wheels, you will be fine, which is OK because Shimano’s wheels are not nearly as good as most other companies out there…
Thanks all for the answers. I’m looking at maybe getting some Flashpoint wheels. So their hubs will work with my collection of 9 speed cogsets?
I believe yes.

While this comment might have been made tongue in cheek…Shimano 7800 is (IMO) the best wheel in it’s range (1500ish gram/clincher/non-aeroish wheelset).
yes.
those wheels are actually compatible with shimano 8-speed, 9-speed, and 10-speed cassettes …
My experience shows incompatibility… I have a 2004 ultegra 9 speed set up and tried to put the cogset on a zipp 404 from a 2007 cannondale Ironman with a 10 speed dura ace setup and the damn cogs won’t fit on the hub! The largest 2 fit fine, but the next one won’t slide on all the way, and the smaller ones slide on even less.
True, weight and performance for the money are pretty good on the new 7800 Shimano Wheelset. I will not argue that. Where I have a big problem with Shimano wheels is working on them. The inboard nipples may provide a bit less rotaional mass, but they make VERY difficult to true the wheels. Especially the rear, where you need to remove the cassette in order to even access the nipples. Not the most mechanic friendly wheels out there…
