All-City 809 Derailleur Hanger Axle Stud and Nut

This kit is specifically engineered for the All-City Space Horse, Gorilla Monsoon, and Cosmic Stallion Titanium frames. It is not a universal part, so please verify your frame model before purchasing.

Yes, this is a complete service kit. It includes the derailleur hanger, the axle stud, and the necessary nut, providing all the hardware required to secure your rear dropout and restore proper drivetrain alignment.

The axle stud and nut are critical for maintaining the structural integrity of your rear dropout. If your hanger has been damaged or bent, there is a high likelihood that the mounting hardware has also experienced stress, so replacing them together ensures a secure, precise fit and reliable shifting.

This kit is constructed from durable alloy. This material choice balances the need for strength to handle drivetrain forces with the necessary precision to ensure your derailleur stays properly aligned.

No, we strongly advise against using this on frames other than the specified Space Horse, Gorilla Monsoon, and Cosmic Stallion Titanium models. Derailleur hangers are frame-specific, and even slight differences in geometry can cause poor shifting performance or damage to your frame.
