CeramicSpeed BSA30 MTB Coated bottom bracket, black
BSA comes from Birmingham Small Arms, aka English Threading. English threading on mountain bikes means a tire with a width of 73 mm and an inner diameter of 34 mm with reverse threading on the drive side. It is the most common thread standard today. This kit allows you to mount 30mm thru-axle cranks, such as those from Rotor or RaceFace, to fit into the tight space of this 30mm spindle. CeramicSpeed coated bearings are hand-crafted with unique CeramicSpeed ceramic balls installed on coated hardened steel rings for longer life and less bearing drag compared to standard bearings. In the box: 2 threaded cups with bearings installed 2 1mm spacers 2 0.5mm spacers Spacer tube 2 dust caps O-ring Long Life Grease Decal
