Hello, I have a 2014 Madone 5.9. I am happy with it except for the brakes. I have got the front caliper to work pretty well. I have read the instructions inside out and am aware of the small 2mm Allen key needed for the squareness of the pad movement towards the rim. But the rear set up leaves a lot to be desired. It is vague feeling and soft, with little vigour as far as caliper release goes. I understand that they are aerodynamic and light but are they really worth the effort? Can I change for sHimano 6810 rear caliper? I assume the Shimano is much heavier though. looks a lot more complicated.

I ended up getting rid of my Madone, I couldn't ever make that brake work well (I was running campag too and they don't offer direct mount). The Ultra or DA direct mount are the best option without spending loads on EE brakes. I never succeeded in eliminating the friction from the brake cable through the frame. I was also limited by crank arm clearance with a Campag setup.

I'm using dura ace brakes with campagnolo super record levers, it's pretty ok, not too bad.

a few alternatives worth exploring - the FSA Direct mount brake, due out in 2-3 weeks, or the Tririg OmegaX. Both are roller cam brakes, with a potential advantage of not moving the lower housing when actuating.

Following up on this thread, I ended up getting the FSA direct mount brakes on my Madone 7 and I am very happy with the result - good feel, modulation, and braking power. Not the lightest set up in the world, but that's not even in the top 5 of my requirements.

Doesn't the EE direct-mount brake fit the Madone? Those are some very impressive brakes. Great modulation and tons of stopping power.

Yes, the EE brakes fit. But they require the pads be run close to the rim, which causes rub when out of the saddle.

here's a pic of the rear brake installed. Hard to tell but I'm running 3-4 mm of pad clearance, so no rub

Hey any idea what those 5.9 brakes weighed when you removed them?
