I do use the brakes.
In fact the brakes have such good power that I can apply them quite late going into a corner, and use them pretty hard.
I am using the Avid Clean Sweep G3 203mm rotor, BB7 road caliper and EBC Gold Pads and Yokozuna reaction cable housing.
This setup has been chosen after trying various configurations. Some with not so good results.
I few things worth noting:
The Yokozuna cable housing and using the most direct path to the with least amount of housing possible makes a huge difference!
The Avid G3 is better than the G2 in dissipating heat (fades later).
The Avid G3 has changed designs since the last one I purchased. The center section is more solid (less material cut out). It still has a lot of holes closer to the outside, but the center section is really solid. Seems smart to me, and hopefully will last a little longer before warping.
I am using the Ultegra 6703 levers now. These levers have more cable pull than the pre-09 Campy levers I was using before. This allows the brakes to be open an extra click or two, which leads to less rubbing than before.
As far as improvements in tandem disc brakes??
I am happy with the 203mm diameter. I would like a caliper that has better build tolerances in that they applied more even pad pressure. Usually my pads wear a little off-plane. The vented disc is another cool idea, something more warp-resistant would be nice.
Essentially a "nicer" version of what's already out there would be nice, a new evolution of the BB7.
