“This is an ultra rare titanium bottom bracket from the mid to late 90′s from small boutique CNC parts builder Bruce Boone … the centre section of the spindle was cut in a twisty corkscrew like fashion, which made for an unimaginably stiff and strong bottom bracket while retaining low weight. It features lockrings for both the drive side and non drive side, which is great for chainline adjustability.”
