All,

Does anyone have experience - the good, the bad, and the ugly all accepted - using Di2 with aftermarket, WW brakes? I am leaning towards Ultegra Di2, but the weight penalty is killing me and I started to think that I might be able to get 100 grams back from using some WW brakes. FYI, I am looking at the Planet X CNC for their weight and price. I am, of course, open to any other brakes especially if shown to work well.

Cheers.

No experiance with Di2, but I love the Planet X cnc brakes with Sram Red. Better than the Sram brakes, lighter, more modulation and better firmness. I'd say go for it. They even come with decent Swisstop green pads

Only downside is they are a bit fiddly in set up to get centered

Big pro, they are BLING and light
