Product Description
BSB's New Bearing Birdcage is the Lightest Steel Bearing
Cage on the Market. This Birdcage has a Newly Designed Hub which allows for Less Bolts and More Clearance. You have the ability to lock this cage up and use it as a two link or you can use it for a swing arm or a good old 4 bar birdcage. The two 1/2 inch thick collars work as retainer rings when used as a 4 bar birdcage, but when used as a 2 link, you must weld them to the axle tube.
