NEW AXLE - NEW BRAKE MOUNTS:

ULTRA-RIGID AND CONFIGURABLE

A custom-made, ultra-stiff race-grade chromoly axle delivers maximum control, steering precision, and predictability.

Interchangeable brake caliper adapters allow brake upgrades for larger brake rotors.

IMPORTANT: All SIRRIS brake mounts are designed for 220 mm brake rotors. Since the Light Bee X comes standard with a 203 mm rotor, it must be upgraded to a 220 mm rotor.
