Purpose and key benefit Brake spacer engineered to improve braking stability by minimizing gaps between rotor and caliper. The tight rotor-structure fit meets brake-disc-specific requirements to ensure consistent, predictable braking on e-scooters and bicycles. Durable, lightweight construction Made from high-strength aluminum alloy for a low weight without sacrificing strength. The alloy resists corrosion and wear to maintain shape and dependable brake function over time. Flexible compatibility Spacer designed to work with a range of e-scooter models and brake-disc assemblies. Adjustable spacing options allow fine-tuning of rotor position for optimized braking performance and reliable fit across compatible systems. Fast, tool-free installation Supports quick, tool-free assembly to reduce installation time. The streamlined mounting approach provides a dependable and effortless solution for electric scooter brake systems and routine maintenance. What makes it stand out Precision fit tailored to brake-disc specifications for reduced rotor wobble and improved stopping feel. Robust aluminum construction that balances corrosion resistance, wear resistance, and long-term dimensional stability. Adjustable, model-flexible design that simplifies integration into different e-scooter brake setups. Designed for quick installation so you spend less time installing and more time riding. Function, compatibility, and performance details Function: corrects and stabilizes rotor spacing to improve brake responsiveness and reduce uneven pad contact. Compatibility: intended for use with brake-disc-equipped electric scooters and compatible bicycles that accept brake-disc spacers; offers adjustable spacing to accommodate variations in hub and caliper setups. Material: high-strength aluminum alloy for lightweight durability and corrosion/wear resistance. Performance: provides a tight rotor fit to reduce play, maintain alignment under load, and promote consistent braking over time. Typical use scenarios 1. Upgrading or replacing a worn spacer on an electric scooter to restore stable rotor alignment and improve braking consistency for daily commuting. 2. Adjusting rotor position when fitting a different aftermarket brake disc or caliper on an e-scooter, enabling correct spacing without lengthy machining or trial-and-error. 3. Routine maintenance in wet or salty environments where corrosion-resistant spacer material helps preserve brake geometry and function. Specifications and compatibility notes Material: high-strength aluminum alloy Function: rotor spacing/stability spacer for brake-disc systems Designed for: various e-scooter models and compatible bicycle brake-disc setups Installation: tool-free, quick assembly for reduced installation time If you need assistance confirming compatibility with a specific scooter model or brake-disc size, compare your current spacer dimensions and brake-disc mounting requirements to ensure the spacer meets your brake-disc-specific requirements.
