Prevent chain drops, protect the frame and derailleur, and keep your ride uninterrupted with this lightweight aluminum-alloy chain catcher designed for road bikes. Key benefits - Prevents chain drop: Guides the chain and stops it from falling off the chainring during shifts or overshifts, reducing the risk of frame damage or derailleur strikes. - Durable and light: Made from aluminum alloy to increase hardness while keeping weight low — easy to carry and adds minimal load to the bike. - Wide compatibility: Supplied with four types of stainless-steel screws in different lengths for strong compatibility with a range of crank/chainring sizes. Features - Compatibility: Fits common road bike chainring ranges, including 34T–50T and 36T–52T. - Mounting position: Installed at the front derailleur position for reliable chain guidance. - Materials: Aluminum-alloy catcher body with stainless-steel mounting screws for corrosion resistance and strength. - Easy installation: Designed for simple attachment in the front derailleur area; hardware included to match different setups. - Protection: Effectively prevents chain movement and falling in case of overshift, protecting drivetrain components. What’s included - Chain catcher (aluminum alloy) - Four types of stainless-steel screws, varying lengths for flexible mounting options Practical use scenarios - Road racing: Keeps the chain on during aggressive shifting and rapid cadence changes, reducing mechanical DNFs and allowing focus on performance. - Training and long rides: Prevents chain drops on rough roads or during high-intensity efforts, reducing interruptions and potential damage. - Commuting and group rides: Offers reliable chain protection on mixed surfaces and frequent stop-start shifting situations. Technical notes - Best suited for mounting at the front derailleur position on road bikes. - Confirm chainring tooth count falls within the compatible ranges (34T–50T or 36T–52T) before installation. - Use the supplied stainless-steel screws to match your specific frame and derailleur mount requirements. Simple, durable, and effective chain protection for road cyclists who want fewer mechanical issues and more consistent rides.
