Threaded pressfit bottom bracket is our latest innovation in bottom bracket technology. Utilizing our CAD (Center Alignment Design) technology, we managed to create a solution that can reduce/eliminate creaking noise caused by imperfect frame alignment. CAD technology also increase efficiency, by aligning cranks better than non-CAD bottom bracket.
