ya know what? the aerodynamics come out similar to the UCI-legal version -- slightly better at high yaw, which us TTers hope never to see!
we'll see what happens.
some manufacturers went back to the beam stuff (which has its own problems); there hasn't been independent validation of just how aero these are relative to the top UCI-legal frames...at least not from what i've seen over the years.
There's
Ventum which I actually kinda like and
dimond which is hideous. There are rumors on ST that Cervelo is coming out with a Dimond type beam bike. If you believe the testing both are faster at almost all yaws than any UCI legal bike.
Of course, we don't know if eliminating the 3:1 rule is going to allow these bikes; technically it doesn't. I believe they still require the standard geometry (2 tubes to the fork). I believe it should; we're well past the point that we need to rely on the that design for safety reasons.
