Union GH-315 Derailleur Hanger Aluminum - Black

Restore smooth shifting and protect your frame with a derailleur hanger, an essential replacement part for certain bicycle models. A bent or broken hanger can ruin your ride instantly, leading to irregular shifting, chain noise, and potentially catastrophic damage to your frame and derailleur. This precisely designed component is your first line of defense and the key to restoring a smooth drivetrain. Designed for a perfect fit, the hanger ensures optimal positioning of the rear derailleur, allowing you to enjoy the precise and reliable shifting you expect from your high-performance bike.

Protect Your Investment

The main advantage of a hanger is its role as a sacrificial component. It is intelligently designed to absorb shocks and detach in a crash, preventing any force from being transferred to the expensive bike frame or rear derailleur. Replacing a small, inexpensive hanger is a far better option than a costly and complicated frame repair. Think of it as a crucial toe cap that protects the sensitive frame tubes of your bike, providing peace of mind on every trail, road, and commute. With a spare hanger, you won’t have to wait weeks for a replacement part after an accident.

Experience Hassle-Free Shifting

A straight derailleur hanger forms the foundation for a perfectly aligned drivetrain. Even a slightly bent derailleur hanger can cause stubborn issues such as unexpected shifting, a skipping chain, and unreachable gears. The derailleur hanger is manufactured with precise tolerances to ensure the exact vertical alignment of the derailleur needed for optimal performance. By installing this replacement part, you restore the original derailleur geometry, allowing you to shift quickly, quietly, and accurately across the entire cassette. Focus on your ride, not on a noisy and unreliable drivetrain.
