Construction and finish: CNC-machined from high-strength aluminum alloy with a black anodized finish for improved corrosion resistance and long-term durability in wet or salty conditions. Lightweight performance: Designed to be about 30% lighter than comparable steel adapters, reducing rotating mass and overall bike weight without compromising stiffness or stability. Compatibility and function: Engineered to integrate seamlessly with flat mount calipers and convert road bike disc brake setups. The precision fit ensures correct caliper alignment and consistent braking performance. Low maintenance: Stable mounting geometry minimizes the need for frequent brake adjustments, making this adapter suitable for riders who prioritize reliable setup and low upkeep. Precision fit and reliability: Lightly machined surfaces deliver accurate tolerances for repeatable installation and consistent brake pad clearance under load. Key benefits — why you need it: Saves weight where it matters most for climbing and acceleration. Maintains stable caliper alignment for predictable braking feel. Withstands weather and corrosion, extending component life and reducing service needs. Typical applications: Competitive road racing — replace steel adapters to shave weight while keeping braking consistency during long efforts. Endurance and mixed-surface rides — durable anodized finish and stable mounting reduce maintenance after wet or gravel sections. Bicycle shops and mechanics — quick, precise swap for converting or upgrading road disc brake systems to flat mount calipers. What stands out: combines high-strength aluminum construction, a corrosion-resistant black anodized finish, and precision machining to deliver a lightweight, stable adapter that fits flat mount calipers and converts road disc brakes without compromising alignment or reliability.
