The bottom bracket is the heart of your drivetrain, yet traditional press-fit shells often suffer from tolerance discrepancies, bearing misalignment, and energy-draining creaks. The Camepro BB86 Ceramic Spiral Lock Bottom Bracket solves these challenges permanently through advanced mechanical engineering. Featuring an innovative internal Spiral Lock threaded interface, both alloy cups thread securely together inside the frame, forming a rigid, perfectly aligned bridge that prevents walking, eliminates frame wear, and guarantees total silence under maximum sprint wattage.
Embodying Camepro’s core pillars of Craftsmanship, Mechanics, and Progression, this bottom bracket brings elite-level engineering within reach of dedicated riders. Equipped with high-precision ceramic bearings and multi-lip weather seals, it delivers frictionless rotational efficiency in all conditions. Available in two dedicated, purpose-built configurations—HG24 (#1512303) for Shimano 24mm spindles and DUB (#1512302) for SRAM 28.99mm DUB spindles—in a sleek anodized black finish.
FEATURES
Spiral Lock Threaded Architecture
Left and right CNC alloy cups thread together internally through the bottom bracket shell, locking the unit firmly in place to eliminate axial play, cup walking, and dreaded press-fit creaks.
High-Precision Ceramic Bearings
Ultra-smooth ceramic balls drastically reduce rotational friction and resist heat buildup, delivering frictionless power transfer and extended bearing life.
Dedicated High-Torque Spindle Optimization
Engineered specifically for Shimano 24mm (HG24) and SRAM DUB 28.99mm systems without sloppy reduction shims, ensuring direct power transmission.
Aircraft-Grade CNC Alloy Construction
Precision-machined from premium aluminum with tight micron-level tolerances and an anodized black protective finish for maximum structural rigidity.
All-Weather Dual-Lip Sealing
Advanced labyrinth contact seals keep road grit, rainwater, and contaminants away from the ceramic internals during demanding riding conditions.
Value-Driven Engineering
Combines the creak-free security of a threaded interface with race-ready ceramic efficiency—without boutique price inflation.
PRODUCT POSITIONING
A premium, creak-free Spiral Lock ceramic bottom bracket engineered for road, gravel, and endurance riders seeking permanent shell stability, absolute quietness, and ultra-low friction on BB86 frames.
TARGET AUDIENCE
Road and gravel cyclists troubled by BB86 press-fit creaking seeking a permanent thread-together solution.
