If you look at this link and scroll down to about halfway, you'll see charts that show time savings of different FLO wheels vs a Mavic Open Pro at different speeds. (Based on their wind tunnel testing).

The figures quoted are for a single wheel only and are independent of rider position etc.

I had a look at the FLO 60 over an IM at 20mph and it gives 537sec (8min 57s). Obviously your rim won't be aerodynamically identical to an Open Pro, but the quoted figure will put you in the ball park.

The 30mm wheel that came with your felt is probably a good bit better than the mavic open pro in the chart above.

If there is no wind, the difference will be relatively small.

If there is some crosswinds, the difference will be larger. Don't expect miracles from it either way.

I don't know the numbers but I run a FLO60 front and disc cover on a 30mm rear training wheel. I know it's close enough to the fastest setups [for me] that I am 100% happy with it and have moved on to finding speed elsewhere.

Comic elites compared to Flo 60 at 40kph in a HIM would cost less than 1 minute. You would only have 1, so I guess it would be less than 1 minute difference.
I decided against it after seeing this information.

Kudos for posting that link. This is amazing.
