To summarize, there are 3 completely separate issues with disc brakes, and there is a lot of confusion on the the conflicting data avail, and the issues all get mixed up (here and other places) constantly:
1) Can a state of the art TT/Tri bike include disc brakes, and is such a bike truly more aero than a optimized rim brake TT bike?
This really needs to stop being said. The P5, Speed Concept, Felt IA, etc. are all OPTIMIZED for rim brakes.
I think I was not 100% clear.
I did not mean a TT bike optimized FOR rim brakes.
I meant a fully OTHERWISE optimized TT with rim brakes.
What does that even mean? Everyone keeps saying that with no ability to define what that means. The front ends of these bikes are all designed around that rim brake. Therefore, it is optimized for rim brakes.
To start,
An optimized disc brake TT bike would be designed to be as aero as possible using a state of the art disc brakes, an optimized disc brake frameset, and an optimized disc brake wheelset (with appropriate hubs and spokes and spoke count), etc.
An optimized rim brake TT bike would be designed to be as aero as possible using a state of the art rim brakes, an optimized rim brake frameset, and an optimized rim brake wheelset (with appropriate hubs and spokes and spoke count), etc.
We....already have all of that.
The P5-X and Andean were designed to be faster than rim brake bikes. You can argue all day long about the test protocol but I'm going by the charts.
Magura brakes are not state of the art? P5 or Speed Concept is not optimized? Zipp 808 NSW and Disc is not optimized rim brake wheels?
We are already at the optimized rim brake bikes and wheels.
