I had
posted previously about the TRP Spyre mechanical disc brake.

The
soon-to-be-introduced TRP Spyre... pushes
both pads together.

Presumably this is also aimed at the road/cyclocross crowd, meaning the leverage ratio might be designed around a drop bar lever’s cable pull. For the uninitiated, having both pads move inward means easier set up and the ability to have a little more space between the pads and rotor when unengaged. It also means one pad isn’t bending the rotor as it pushes it into the static pad like on current calipers like Avid BB7 and Hayes CX5, among others.
TRP claims the new Spyre and Spyre SLC cable actuated disc brakes are more than 20mm narrower than Avid's BB7.

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) – 61g lighter than the new Avid BB7 SL – 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.
