I'm considering their trispoke for my TT bike. I own an old school HED trispoke, the real deal, but it can only stay aero taking a 19mm tire.
Given the width of the Superteam, $250 may be worth taking a shot. If they seem crap, toss em on Ebay and lose $100 for the experiment.
I'd love to get up to a 23mm up front on a trispoke. Some roads just aren't conducive to a 19mm tire no matter how skinny you are.
