Bicycle Derailleur Hangers

Ensure your drivetrain is perfectly aligned with our Bicycle Derailleur Hangers collection. Because a straight derailleur is absolutely vital for the tight tolerances of modern multi-speed cassettes, a bent hanger can cause skipped gears, chain drops, or worse—sending your derailleur into your spokes. Our collection offers an expansive index of precision-engineered replacements, from CNC-machined 6061-T6 billet aluminum upgrades that provide crisper shifting than cast OEM models, to the revolutionary SRAM Universal Derailleur Hanger (UDH) standard. Whether you are replacing a snapped hanger after a crash, upgrading your gravel rig for stiffer shifting, or simply stocking a vital spare in your hydration pack for a remote bikepacking trip, our selection delivers the precise geometry required to keep your rear mech tracking perfectly.
