    Why no dual moving pistons mech calipers ?

    Obviously one downside of mechs are their single side moving pad. Which means the rotor has to flex unless you run the inside pad fully contacting the rotor.

    But why aren't they making a BB7 version with actuation arm for both in and out pads ? I know it would be heavier and maybe more expensive, but the advantages of a mech calipers would extend even further.

    Just a though. There's probably already a few reasons why it's not out yet.

    ^ They're both the same brakes, just labeled different and different color. I have the WinZip branded one. They work alright. Never really had trail time on them nor comparison to BB7 though.
    These works more like a caliper on a car where one piston moves to move the whole caliper that pinches the rotor. Whereas on a hydro, the caliper is fixed and both pistons move.

    Would be interested to get a BB7 performance-level version of these.
