Armstrong Alloy System Mast Bottom Bracket

Armstrong Alloy System Mast Bottom Bracket

The Armstrong Alloy System Bottom Bracket is the engineered foundation of the Armstrong Foils setup — built to deliver uncompromising stiffness, strength, and precision through every ride and every turn. Designed as part of Armstrong’s modular foil platform, this bottom bracket forms the critical connection between mast and fuselage, translating every ounce of input into seamless glide, lift, and control.

CNC-machined from aircraft-grade aluminum, the Alloy System Bottom Bracket offers a rock-solid interface that resists torsional flex while keeping overall weight impressively low. Its precisely tuned geometry ensures a perfect, secure fit with Armstrong’s modular components, maintaining structural integrity even under the heavy loads of high-speed carving, pumping, and jumping.

Finished with a hard-anodized coating for maximum corrosion resistance in saltwater environments, it’s a piece of hardware built to last — session after session, season after season.
