Rear Derailleur Hanger


Rear derailleur hangers for Chinook tandem frames. CNC machined titanium or aluminum.

SKU: N/A Categories: , Tags: ,

Replacement rear derailleur hangers for most Chinook frames. These will fit other frames that use Paragon Machine Works 1 1/2" round dropouts for 12mm thru axles.

Choose a thread size (M12 x 1.5 or M12 x 1.0) to match your rear thru axle.

Length listed is the distance between the axle and the derailleur mounting bolt. "Standard" mounting distance for rear derailleurs is 28 to 35mm; and most rear derailleurs function well in that range. Choose the 45mm hanger for using larger cassettes (with a 40T to 45T large cog) with a "road" rear derailleur.

This product includes the hanger and its fasteners only.
