Are you competing for podium? The difference between pair of 808 and 808/disc is around 5 watts on paper.

I have a Speedmax myself and went for the Zipp Super 9.

When fiddling around marginal gains, choosing an appropiate tire will give nearly the same time saving.

I want to go as fast as possible yes.. ;)
but from the aero data from tour magazine the Speedmax was fastes with 808 in front and back.. almost identical as P5six with 808/Disc
With 808 front and disc back it was a bit slower actually.. while all others was faster with Disc in back
and that is the reason I`m asking :)

Does the test state which tires that were used? That could be a confounding factor.

That result is sufficiently odd enough that I wouldn't trust it.

The 808 can be faster sometimes at certain yaw angles, but that big of a difference, at all yaw angles, is odd.

The whole test from Tour magazine http://www.tour-magazin.de/...hrraeder/a24253.html

Yeah I think it is odd to... But tour magazine usually have good tests?

reasonable, but anyone can make mistakes
or stuff can be missed in translation

All wheels where mounted with Continental Grand Prix TT.
they tested with Zipp 808 set, Zipp 808 front and Super-9 back and Zipp 808 front and Lightweight disc in back. and still the 808 Set was measured the best.
they where using dummy legs on all setups. they also did a note on that all bikes performed the best with Zipp 808 front and Super-9 disc in back except Canyon Speedmax which performed best with 808 Front and back.
I also feel that its verry strange that a 808 set is faster than disc setup.. but from what I read in the test it really looks like it is? or should I just asume that the test is wrong and go with Disc? :) is it to good to be true ?
I ordered the Speedmax 9.0 SL that comes with 404 front and 808 back. bought that one since I needed a extra pair of wheels for my RR bike. so since I want to go as fast as possible on the bike I really want the optimal wheels for the bike so if that its 808 pair or 808/disc I will put that on my shoping list.
what are the real Pro/Cons on 808 set vs 808/disc ?
