I have a relatively new set of aces, came pre-bled. Mine are make contact about 25% of the way through the stroke, and are fully locked at 50%. When I say stroke, I mean from start position to the bar. Some people think this is too far to start engaging. I really like how they work, feels like a car brake to me, lots of room to modulate the power.
Also the pad to rotor distance is about as low as I would want it. Approximately 0.030".
