Machined aluminium alloy hanger designed to match Trek Gary Fisher models 322175 and 318610. Supplied screws and a smooth finish enable straightforward replacement and help protect frame and derailleur during a fall.


Protects frame and derailleur alignment - with a replaceable hanger design

The hanger connects at the top to the frame and at the bottom to the rear derailleur, acting as a sacrificial link in a fall. Machined aluminium alloy offers precise tolerances so the hanger aligns correctly with the drivetrain.

Reduced risk of costly frame or derailleur damage after impacts, because the hanger takes the force and can be replaced quickly.

Straightforward fit for on-the-road repairs - with included screws and model matching

The package includes a set of screws and carries the specific model numbers 322175 and 318610, so compatibility depends on matching the existing hanger. Smooth surfaces and accurate machining make removal and refitting simpler.

Quicker repairs and fewer visits to a bike shop, provided the existing hanger matches one of the listed model numbers.

Lightweight and robust replacement - thanks to aluminium alloy construction

Aluminium alloy supplies a balance of low mass and structural strength, with a finished surface that resists wear. Lightweight construction avoids adding unnecessary weight to the rear end of the bike.

A durable, light spare that maintains ride characteristics while replacing a damaged hanger, useful for regular cyclists and commuters.
