A press-fit bottom bracket assembly tailored for BB86 bicycle frames (86.5 mm shell width, approximately 41 mm inner diameter), engineered to accommodate SRAM’s DUB crank spindle (28.99 mm diameter). It features CeramicSpeed hand-built ceramic bearings with your choice of Standard (hardened-steel races) or Coated (metal-coated hardened-steel races) versions. The kit includes two bottom bracket cups with integrated dust covers, a spacer tube, a plastic sheet, spacers (four 1 mm and four 3 mm), CeramicSpeed All Round grease, and a sticker/decal sheet. The net weight per manufacturer is 77 g, gross weight is 206 g. An alternate trusted retailer reports a lower weight of 59 g net and 116 g gross, but I’ll prioritize the manufacturer. Inner diameter is not explicitly stated but is commonly BB86 standard (~41 mm).
