Introducing the Aether Labs MTB Blade Guard Downtube Protector (patent pending)

Mountain bikes are major investments, often ranging from $3,000 to $10,000 or more, and pushing them to their limits means risking structural damage from high-velocity rock strikes or heavy bottom-out impacts. Traditional adhesive films might protect your paint, but they offer little to no kinetic energy dissipation and are prone to peeling. Bolted guards are heavy, trap mud, and only fit specific frames, while rubberized padding can snag on obstacles and tear off.

The Blade Guard is the ultimate solution: a professional-grade, interlocking frame protection system that delivers heavy-duty kinetic impact defense without sacrificing weight, aesthetics, or cross-compatibility.

What It Is & How It Works

The Blade Guard was primarily designed as downtube protection for mountain bikes.

It utilizes an innovative two-layer 3D-printed thermoplastic construction to provide unparalleled protection:

  • The Damping Layer: The inner layer is constructed from flexible TPU featuring an advanced "gyroid" internal wave pattern. This structure absorbs and dissipates the kinetic energy of trail impacts before it can reach your frame, all while utilizing air gaps to keep the guard incredibly lightweight.

  • The Impact-Resistant Layer: The rigid outer shell is made from a tough TPU/Nylon hybrid designed to deflect high-velocity projectiles and debris.

Because the system is modular, you can seamlessly snap together a front guard, internal sections, and a rear guard to create one continuous shield or break them up into smaller, targeted pads for high-wear cable rub zones. Length is fully adjustable to fit any frame length, resulting in a custom fit.

Riders can choose between different levels of protection depending on their needs:

  • Gladius - XC (Coming soon)

  • Katana - Enduro/aggressive trail (2026 Launch)

  • Claymore - DH heavy duty protection (Coming soon)
