A precision-engineered press-fit bottom bracket designed for BB86 bicycle frames featuring an 86.5 mm shell width and 41 mm inner diameter. It accommodates SRAM’s DUB crank spindle (28.99 mm) and is equipped with CeramicSpeed Coated bearings—ceramic balls running on hardened-steel races enhanced with a metallic coating for superior durability, corrosion resistance, and ultra-low friction. The kit includes two cups pre-installed with coated bearings, integrated dust covers, plastic sheet, spacers (four 1 mm, four 3 mm), a spacer tube, CeramicSpeed All Round grease, and a decal. Manufacturer data lists the net weight at 77 g and gross weight at 206 g. Some alternate retailers report significantly lower weights (e.g., 59 g net, 116 g gross), but the manufacturer’s figures take precedence.
