BB ALPHA Road Bottom Bracket - EVO386, 86.5mm, For DUB Spindle

CeramicSpeed BB ALPHA Road Bottom Bracket – EVO386, DUB Spindle is engineered for riders who demand lasting performance, low friction, and precise power transfer. Built with hardened stainless-steel races and hand-assembled grade-3 Silicon Nitride ceramic bearings, this bottom bracket is designed to deliver a smoother, more efficient ride that stands up to years of hard miles.

The BB ALPHA series takes CeramicSpeed’s proven bearing technology even further with improved sealing and durability. The redesigned bearing placement and precision dust covers enhance protection from moisture and grit, offering up to 500% better resistance against the elements compared to standard bottom brackets. Every unit is built in Denmark and backed by a lifetime warranty, reflecting the brand’s commitment to quality and performance.

Key features:

• Low-friction performance from hand-built ceramic bearings that reduce drag and improve pedaling efficiency.
• Enhanced sealing system with stainless-backed custom seals for superior protection against dirt and moisture.
• Hardened stainless-steel races provide corrosion resistance and a smooth interface for ceramic bearings.
• Advanced bearing placement moves the bearings outward for improved stiffness and load handling.
• Redesigned internal race support delivers better pre-load stability and long-term reliability.
• Lighter 7075 aluminum cups and simplified spacer tube design for quick installation and a 10% weight savings over previous versions.

The result is a bottom bracket that maximizes every pedal stroke, stays smoother longer, and keeps your drivetrain running at peak efficiency—ride after ride.
