Do they vent brake fluid onto your bars by way of a breather valve like the previous designs? If the breather port is against the bars they will, pretty stupid design.

No support, no parts, that's a problem. If history repeats I would buy Curas, enjoy all those good aspects and then when a seal fails throw them away because the company does not have a supplier and is unwilling to stand behind their product. If you treat them as disposable I guess they're great, just a tad expensive.

I wouldn't fool with Formula. Flawed designs, zero customer service and no replacement parts.

Formula should not even be a consideration. I have two sets of Formula brakes that cost over a thousand dollars sitting on a shelf not working. Formula does not provide any service. The brakes have their breather port against the bars so that they constantly weep brake fluid on your carbon bars. This company looks so good on the surface, but their designs are flawed and they don't stand behind their product. I have The One and R-1, both top end brakes that failed in the field. Keep Formula out of my bike shop thank you.
