They are called "pressure recovery" pants for a reason.

Default Hub caps vs huge wheel pants

To answer my own question, the hub caps cost me 1.5kts over the "pressure recovery" wheel pants. For me, the ease to check air pressure and also use the tire as a step to clean the windscreen is well worth that whopping 1.5kts.

I think you haven't done enough testing to actually know........

I agree the leg fairings are worth the biggest speed increase, but the wheel pants are good for more than 1.5 Kts

Default Agree

That's probably true Scott. Maybe my wheel pants were not constructed tight to the wheels to begin with or maybe some other variation somewhere else in the process. The hub caps are painfully simple. Over the next several months I'll keep a watch on the data and see if I can detect a change.
