TRP Spyre Road/CX Mechanical Disc Brake Caliper Post Mount Black

One of the most respected mechanical disc brake calipers for road, gravel, cyclocross, and touring bikes.

The TRP Spyre mechanical disc brake caliper uses a true dual-piston design where both brake pads move simultaneously for more even rotor contact, smoother modulation, and stronger braking performance than traditional single-sided mechanical systems. Designed for cable-actuated road levers, the Spyre has become a favorite for gravel bikes, touring bikes, cyclocross builds, and riders wanting reliable braking without the maintenance complexity of hydraulics.

Key Functional Details

• Dual-sided mechanical actuation moves both brake pads evenly
• Compatible with all short-pull road cable brake levers
• Built-in barrel adjuster simplifies setup and cable tension adjustment
• Independent pad adjustment for easy maintenance
• Strong modulation and predictable braking feel
• Excellent option for gravel, touring, and cyclocross applications
• Compressionless housing highly recommended for best performance
