I have swapped over to my road wheelset for the TT bike after "learning" for long enough to ride a disc/trispoke combo in some wind.
I knew tire choice matters, but I took off the Conti sprinter I had on the rear disc.........that POS is pretty much almost a solid piece of truck tire rubber compared to the Vittoria Corsa Speed I replaced it with. Like, it felt worse in my hand than a clincher Gatorskin. Geeeez.
I'm seriously hoping that was giving me some mega bad watt loss and my speed will come up a touch on the new tires.
Rear, 23mm Corsa Speed. Front, 19mm Pista G+. Gotta start gluing the trispoke tonight after some kind of hellish workout.
