Modern aero frames utilize asymmetrical bottom bracket architectures to maximize drive-side stiffness without compromising chainline precision or frame clearance. The Camepro T47A Ceramic Bottom Bracket is engineered specifically for 77mm / 79mm asymmetric T47 shells (Drive-Side External / Non-Drive Side Internal), delivering a creak-free junction for elite road machines like the Factor OSTRO VAM, Cervélo BBright T47 conversions, and modern aero platforms.
Embodying Camepro’s founding pillars of Craftsmanship, Mechanics, and Progression, this bottom bracket proves that high-end frame compatibility and ceramic efficiency shouldn’t carry an inflated boutique markup. Built around ultra-smooth, high-precision ceramic bearings and paired with aircraft-grade CNC alloy cups, it drastically minimizes rotational drag while preventing frame-damaging wear. Available across dedicated T47A 24 (Shimano 24mm), T47A DUB (SRAM 28.99mm), and modular T47A 30 (Total) configurations, it ensures instantaneous acceleration and all-weather reliability under maximum sprint wattage.
FEATURES
T47A Asymmetric Shell Optimization
Custom-engineered for 77mm/79mm asymmetric threaded shells—placing the Non-Drive Side bearing internally (Inboard) and the Drive-Side bearing externally (Outboard) for flawless chainline alignment.
High-Precision Ceramic Bearings
Ultra-smooth ceramic balls drastically reduce rotational friction, delivering fluid pedaling dynamics and extended bearing longevity under high-wattage sprint loads.
Micron-Tolerance CNC Machined Threads
Precision-cut M47 x 1.0mm alloy threads ensure silky installation, precise concentricity, and a rock-solid, creak-free interface that protects carbon frame threads.
Dedicated Spindle Configurations
Available in dedicated T47A 24, T47A DUB, and T47A 30 (Total) models to support Shimano 24mm, SRAM DUB 28.99mm, and 30mm cranksets without sloppy shims.
All-Weather Dual-Lip Sealing System
Advanced labyrinth seals shield the internal ceramic elements from road spray, grit, and moisture during demanding racing conditions.
Value-Driven Engineering
Delivers elite-level ceramic smoothness, rigid mechanical alignment, and lasting durability without boutique price inflation.
