## Overview

The TRP Spyre Mechanical Disc Brake Caliper is a lightweight, dual-piston cable-actuated brake designed for precise, balanced stopping power. Its slim 40mm profile and 146g weight make it ideal for drop-bar bikes, offering easy setup and fine-tuning with a built-in cable adjuster. Compatible with all cable drop-bar levers, it delivers reliable performance for riders seeking both efficiency and style.

## Description

The Spyre, a mechanical disc brake that offers superior performance with incredibly easy setup. This is a dual piston actuated mechanical disc brake caliper which provides precise clamping force. This translates into even pad and rotor wear because the rotor does not need to flex to one side during braking. We added a simple cable barrel adjuster to make fine tuning easy. All of this in an incredibly thin 40mm, 146g package, that works with any drop bar levers on the market. Rotors and adapters are sold separately. For tandem bikes, we recommend the Spyre caliper paired with our 2. 3 mm thick rotors. This will give optimum stopping performance for you and your partner.
