That.

You have a set of old Zipp wheels. That's what S60/S80 are. Newer wider rim wheels with dimples are faster but only marginally so.

Get a cover for the rear wheel. Call it good.

Thanks! I just ordered one.

Bummer, but it seems like when you have a decent set of aero wheels, time and $$ are better spent elsewhere. The only bummer is that with the older narrow wheels, you take more of a hit running wider tires.

But if you put on an Attack or a Conti SS, you won't be giving up much to a new 404/808.

My wife races on a set of silver/black/white S60's that used to be mine, but match her bike better.

Happy with the result, used both tape and the fasteners. Now I only need to wait for spring to arrive..
