Derailleur hangers exist to fail. That's not a design flaw—it's the entire point. When your rear derailleur takes a hit from a rock, a crash, or an unfortunate encounter with your wheel, the hanger sacrifices itself so your frame dropout stays intact. The Specialized 18 Road Disc Thru Axle Derailleur Hanger is the replacement part for this specific sacrificial component, machined to match the dropout geometry on compatible Specialized road frames with thru-axle rear ends.

The hanger ships in either black or silver anodized finish depending on your frame's original specification. Specialized machines these from aluminum to precise tolerances because hanger alignment directly affects shifting performance—a bent or poorly fitting hanger creates ghost shifts, chain noise, and indexing problems that no amount of cable tension adjustment will fix. If your shifting has degraded after an impact or you notice the derailleur cage sitting at an angle, the hanger is the first component to inspect and often the cheapest fix.

Compatibility requires verification against your frame's model year and specific build. Specialized uses different hanger designs across their road lineup, and the "18" designation indicates this particular geometry. Check your current hanger's part number or reference Specialized's compatibility charts before ordering. Installing the wrong hanger results in poor shifting at best and potential drivetrain damage at worst.... Read More
