Feature & Benefit Prior to founding Joseph Kuosac, Joe spent ~20 years designing and manufacturing automotive and heavy-duty industrial products of the highest quality and reliability standards. He incorporated relevant design theories and applied the best professional practices he learned into Joseph Kuosac products. The Joseph Kuosac Bottom Bracket is designed with drive-train philosophy in mind and built-in the ability to accept uneven and alternating stress from peddling between left and right. “I think of your feet to the bottom bracket as crankshafts to automobile engines”, says Joe.
