Key benefits — why you need this adapter Enables seamless mounting of shifters on EV brake levers so you can install or upgrade controls without fitment issues. Durable construction resists wear and corrosion for longlasting performance during regular use. Hollow, lightweight design reduces added weight while maintaining strength and a clean, professional look. What it does Converts shifter mounting interface for compatibility with EVstyle brakes, allowing shifters to be attached securely and aligned correctly. Precisionmachined surfaces ensure consistent fitment and reliable operation under load. Materials and finish Constructed from aluminum alloy with stainless steel components where needed for added strength and corrosion resistance. Finished using CNC cutting and anodic coloring processes for accurate tolerances and a resilient, attractive surface. Compatibility Compatible with EV brakes and specifically suitable for brake models: 4100, 6100/6120, 7100/7120, 8100/8120, and 9100/9120. Performance and engineering highlights CNC cut for precise geometry and repeatable fit. Hollow design minimizes weight without compromising rigidity. Anodic coloring improves surface durability and resists fading or chipping. Practical use scenarios Replacing a damaged or worn adapter on a commuter or training bike to restore proper shifter mounting and rideability. Upgrading controls on a road or gravel bike to use EV brakecompatible shifters while keeping a lightweight, durable setup. Building or customizing a bike where precise shifter alignment and a clean aesthetic are important for comfort and performance. Installation and fit notes Designed to provide a secure, seamless mount for shifters on compatible EV brake levers. Follow manufacturer torque and assembly instructions for safe installation. Why this adapter stands out Combines aluminum alloy and stainless steel for a balance of light weight and durability. Precision CNC machining and anodic finish deliver reliable fitment and lasting appearance across the listed brake models.
