The Art and Science of In-House Componentry

Branta builds wheelsets, cranksets, integrated power meter systems, electric motors, suspensions, software, and much more.

These are the core performance systems of the bike, developed alongside the frame and tuned perfectly across the entire platform.

Not trend-driven. Not spec-sheet decoration. Built for structural limits, real riders, and complete-bike performance.

Carbon Wheelsets Raced by the Pros

Anyone can chase grams. Branta builds for the harder balance: wheels that accelerate quickly, hold their line at speed, transfer power cleanly, and stay composed when the road gets rough.
This is proudly proven at elite levels with the Spanish UCI Women's ProTeam Laboral Kutxa-Fundación Euskadi.

Built-in Power Meter

Branta cranksets are engineered for stiffness, low weight, vibration control, and efficient power transfer, giving X-LAB bikes a more connected feel under every load.
With a built-in power meter, the integrated measurement comes standard where it belongs: inside the system, not added later.
Direct-drive. Disc-spider measured. IPX7 waterproof reliability. Tested and validated across millions of data points.

High Performance Motor: Branta X800

Power is only impressive when it feels natural.

Branta mid-drive motors are engineered for high torque, smooth control, quiet operation, and stability in real-world riding.

The Branta motor is developed with thermal analysis to optimize for cooling. And, weighing at just 4 pounds the X800 motor delivers the same torque at nearly half the weight of leading industry motors.

Compact. Responsive. Seamless. It's power that moves with you, not against you.
