Specialized Derailleur Hanger

No, this specific hanger is engineered exclusively for 2018 and newer Tarmac and Venge models equipped with disc brakes and thru-axles. It will not fit older rim-brake models or other Specialized road frames.

Using an OEM part ensures the exact geometry required for your bike's frame, which is critical for precise derailleur alignment. Aftermarket hangers often have slight variations that can compromise shifting accuracy and potentially damage your drivetrain.

This component is designed for Shimano standard shifting configurations. While the physical mounting interface is specific to the frame, the derailleur attachment point is optimized for Shimano's geometry.

Yes, keeping a spare hanger in your saddlebag is a smart practice. Because hangers are designed to bend or break to protect your frame during an impact, having a replacement on hand can save your ride if you experience a crash or a derailleur strike.

If you notice inconsistent shifting, ghost shifting, or if the derailleur cage looks misaligned with the cassette cogs, your hanger may be bent. A visual inspection from the rear of the bike often reveals a slight tilt, but a shop-grade alignment gauge is the only way to confirm it definitively.
