Five33’s answer to the sub-50g 5″ open class racing frame.

Lightswitch ULTRA

Five33’s latest take on a frame built for maximum performance. Winning the French National Championship before launch (Piloted by Darkex) the Lightswitch Ultra has proven to give pilots the competitive edge and confidence they need to succeed. Utilizing our Lightswitch V2 Spine System for stiffness, the frame remains stiff even at its sub 50 gram weight. The top pilots and community put their thoughts out in the world as to what they wanted from the next generation of Five33 frames, we couldn’t be happier with the result.

Everything great about our LIGHTSWITCH V2 but Smaller and Lighter!
