I had posted previously about the TRP Spyre mechanical disc brake.
The soon-to-be-introduced TRP Spyre... pushes both pads together.

Now, more info today at Bike Radar, it includes news of a weight weenie version weighing only 141 grams. The Spyre really looks like an advancement on the venerable Avid BB7.
TRP Spyre road/CX disc brakes - full details
Just prior to the public unveiling here at the Taipei Cycle Show, TRP today released official information on the new Spyre road/cyclocross disc brakes that we previewed a few weeks ago.... TRP says that the cable-actuated Spyre will deliver 20 percent more power, 20mm more ankle clearance, 40g less weight, and more even pad wear than a standard BB7 thanks to its symmetrical dual-piston design.
Claimed weight on the complete standard Spyre is just 239g (front caliper with 160mm rotor and hardware) Ė 61g lighter than the new Avid BB7 SL Ė while the previously unofficial Spyre SLC cuts that down to 141g thanks to a molded carbon fiber arm.
The top-end TRP Spyre SLC incorporates a molded carbon fiber cable arm that brings the claimed caliper weight down to 146g.
