Use Edson's double hub sprockets when space will allow; their extra length will spread the load. They are the same as the single hub sprockets but have a hub on both sides of the sprocket teeth with one side knurled for a brake. The Double Hub Sprocket is the standard sprocket used in Edson Pedestals with side mount brake. Part #855-2-11SB replaces part #855-2-11BR and includes 2 5/16"-18 x 1/2 cone point set screws that replace the drive pin originally used with steerers that used the 855-2-11BR sprocket.
