The Tektro MD-C550 mechanical disc brake caliper represents the ideal solution to equip your road and gravel bikes with a high-performance and reliable disc brake system, while retaining the simplicity of cable actuation. Specifically designed for short pull road levers, this Flat Mount dual-piston caliper delivers consistent and modular braking power, perfectly suited to long descents and demanding conditions.

Technical Overview

The MD-C550 adopts a dual-piston architecture to ensure balanced distribution of clamping force on the disc. Its one-piece aluminum body ensures rigidity and lightness with only 155 grams on the scale. The Flat Mount system integrates perfectly with modern road/gravel frame and fork standards, offering a low profile and clean aesthetics. Compatible with 1.8 mm thick discs, it works optimally with Shimano, SRAM, MicroSHIFT and Campagnolo road pull levers.

Technical Highlights

• Dual piston for balanced braking: The dual-piston configuration ensures simultaneous engagement of the pads on each side of the disc, ensuring progressive modulation and consistent braking power without vibration.
• Mechanical cable actuation: Simple maintenance, universal compatibility with mechanical road groups and easy adjustment on the go — ideal for bikepacking and long-distance rides.
• Low-profile Flat Mount: Discreet integration into modern frames and forks, reduced bulk and improved aerodynamics compared to Post Mount installations.
• Independent pad adjustment: Precise adjustment of each pad for optimal centering and even wear, coupled with an integrated cable adjuster for tool-free micro-adjustments during rides.
• Ceramic metal pads included: Compound offering excellent thermal fade resistance and superior longevity, even under intensive use.

Compatibility and Installation

• Compatible levers: All short pull road levers (short pull / standard pull): Shimano road (105, Ultegra, Dura-Ace mechanical), SRAM DoubleTap mechanical, MicroSHIFT, Campagnolo mechanical.
• Not compatible with long pull MTB levers without a pull adapter.
• Flat Mount installation: Installs directly on frames and forks equipped with standard Flat Mount mounts. Adapters available separately for different disc diameters (160 mm, 180 mm, 203 mm).
• Disc thickness: 1.8 mm (road standard). Discs sold separately — choose the appropriate diameter according to your frame/fork.

Performance and Use Cases

The Tektro MD-C550 is aimed at road, gravel, cyclocross and bikepacking cyclists seeking the reliability and power of disc braking without switching to hydraulic. Its consistent braking power and precise modulation give you confidence and control on all terrains, from technical descents to emergency braking in the peloton. Mechanical actuation greatly facilitates maintenance, on-the-road repairs and ensures maximum compatibility with existing groupsets.

Care and Maintenance

• Simplified maintenance: No hydraulic bleeding, easy cable and housing replacement, quick adjustment via the integrated adjuster.
• Cable quality essential: Use quality cables and housings (compatible with road braking) and take care with routing to optimize force transmission and modulation.
• Bedding-in required: Perform bedding-in of pads and disc over the first kilometers to develop maximum braking power.
• Regular inspection: Check pad wear, disc condition and cable tension before each long ride.

Tektro Origin and Quality

Manufactured by Tektro Technology Corporation, a Taiwanese family business founded in 1986 and world leader in bicycle braking (3rd largest manufacturer worldwide behind Shimano and SRAM). With production facilities in Taiwan and China, Tektro produces 13 million brakes per year and equips the largest bicycle brands. The MD-C550 benefits from this expertise of over 35 years in developing high-performance and reliable braking systems.
