BONIN Rondo RSP 005 Derailleur Hanger | Precision Transmission Spare Part

Restore your bike´s performance and protect your investment with the BONIN Rondo RSP 005 Derailleur Hanger. This essential transmission spare part is meticulously engineered to be the perfect direct replacement for specific Rondo bicycle frames, ensuring your gear shifting is as crisp, reliable, and accurate as the day you first rode your bike. A bent or broken derailleur hanger can ruin a ride and lead to poor shifting, chain drops, and even catastrophic damage to your frame or rear derailleur. The RSP 005 is your first and best line of defense, designed to get you back on the road or trail with confidence and peak performance.

Key Benefits for the Discerning Cyclist

The primary function of the BONIN Rondo RSP 005 is to provide critical protection for your bicycle´s frame. It acts as a sacrificial component, engineered to absorb the force of an impact from a crash, drop, or trail-side obstacle. By bending or breaking under stress, it saves your far more expensive and integral frame dropout from permanent damage, turning a potentially ride-ending disaster into a simple and affordable fix. Beyond protection, a perfectly straight hanger is the foundation of a high-performance transmission system. This precision-made part ensures perfect alignment between your rear derailleur, cassette, and chain, allowing for flawless gear changes, eliminating frustrating ghost-shifting, and maximizing the efficiency of your drivetrain.

Main Features

Engineered for a seamless fit and long-lasting reliability, the BONIN Rondo RSP 005 boasts a range of features designed for optimal function. Its construction from a high-grade aluminum alloy provides the ideal balance of stiffness for precise shifting and ductility to absorb impacts effectively. The manufacturing process ensures exact tolerances, guaranteeing that it aligns perfectly with your frame´s mounting points and your derailleur´s B-knuckle. This direct-fit design makes installation straightforward, allowing you to quickly replace a damaged part and minimize downtime. Its lightweight profile ensures that this critical protective component adds no discernible weight to your high-performance Rondo machine.

The Protective ´Toecaps´ of Your Drivetrain

Think of the derailleur hanger as the protective toecap for your bike´s most vulnerable transmission area. The hanger´s tip, where the derailleur mounts, is the critical interface that dictates shifting accuracy. The BONIN RSP 005 is designed so that this specific point provides a stable and rigid platform for the derailleur under normal pedaling loads, yet serves as the designated failure point under excessive side-load or impact. This intelligent design ensures the integrity of your entire rear triangle, safeguarding your frame and keeping your rides safe and uninterrupted.
