DERAILLEUR HANGER
Replacement 323 Derailleur Hanger
6061-T6 aluminium CNC machined. Compatible with all bikes that use the Specialized 323 Derailleur Hanger.

THE REDESIGNED HANGER HAS A BUNCH OF IMPROVEMENTS INCLUDING:
▸ Hard mounted derailleur - improving hanger strength, alignment and thread durability.
▸ Sharktooth design which stops the chain from running past the small sprocket and onto the frame during the shift.
▸ Removing the sandwich style frame mounting, instead using a UDH style locking nut which locks the hanger to the frame.
▸ Strategic material removal to achieve a predicted failure point of the hanger during an accident to help save the derailleur and frame.
Why is our SHARKTOOTH Derailleur Hanger better than the Specialized 323?
I created this replacement derailleur hanger for Specialized 323 because I had continuous trouble with the chain dropping off the small gear. This was scary and dangerous, forcing me to abandon the run.
I quickly realised that this issue is prominent. Every single bike I’ve seen with the stock 323 Specialized Sandwich derailleur hanger has scratches on it, proving it has dropped off the small sprocket.
I also found that over time the derailleur bolt would come loose and I would constantly have to tighten it.
On closer inspection, what was happening involved the sandwich design at the derailleur bolt. The bolt goes through an oversized hole, causing it to deform/burr inward, which resulted in the derailleur binding against the hanger, not allowing it to swing backwards as its intended operation.
Also, the Sandwich design does not allow for the slight misalignment of the machined surfaces on the dropout. This caused the M3 bolt to pull its thread out when tightening the wheel Axle.
So, I set out to design a new replacement Specialized 323 derailleur hanger – without all of the issues. After a few prototypes I perfected the final version and it is now ready for you to install and enjoy the ride!
