CeramicSpeed BB ALPHA Bottom Bracket - T47 86mm For SRAM DUB Spindle Gravel BLK

Riders pushing gravel or adventure bikes need a bottom bracket that stays smooth, even after miles of rough roads and muddy weather. The BB ALPHA uses hardened stainless-steel races with grade-3 Silicon Nitride ceramic balls, delivering ultra-low friction and up to 500% better moisture protection, so you can ride further with less maintenance. Lighter aluminum cups and a simplified spacer design shave weight and simplify installation, while handbuilt Danish craftsmanship backs every unit with a lifetime warranty.

Who is this for?

Gravel riders and endurance cyclists who value reliability in challenging conditions, SRAM DUB setups, and a bottom bracket that minimizes drag and maintenance. If you want a durable, high-precision BB that helps you maintain speed on long gravel routes and snowy commutes, this is for you.
