Gulo Composites is a brand dedicated to pushing the boundaries of cycling performance through innovative carbon composite technologies.

About GULO

The GULO Composites brand was launched in May, 2020 by KEIR Manufacturing. GULO Composites is a brand dedicated to pushing the boundaries of cycling performance through innovative carbon composite technologies. We design and manufacture lightweight, ultra-smooth carbon wheelsets that empower riders of all levels to achieve peak performance and experience the thrill of the ride.

GULO WHEELS

Wheels have progressed slowly through the years. While traditional wheel designs have limitations like stress risers, tension imbalance, and impact vulnerability, the Gulo wheel system takes a revolutionary approach, tackling these challenges head-on for a superior riding experience.

A wheel’s most integral and industrious component is the spoke; the link that ties it together and brings the wheel to life. At the heart of the Gulo wheel system lies the incredibly strong and durable Gulo composite G-Spoke with Ride Smooth Technology. The design intent of the Gulo wheel system was motivated by this unique composite spoke, which propelled the rest of the wheel into an optimized and balanced performance package.

Developed, engineered, and tested with impact resistance and fatigue life at the forefront, the G-Spoke is truly revolutionary . Exceptional weight, durability, stiffness and vibration damping have never been synergized in such an application, until now.

The G-Spoke body is designed, engineered, and manufactured all under one roof in Brevard, North Carolina, USA. The use of composite materials with our advanced triaxial braiding techniques offers distinct advantages over traditional metal spokes by reducing vibrations by 7.5%.

Our triaxial braiding technologies allows our team of engineers to adjust braid orientation and introduce multiple types of fibers for a hybrid composite structure. After years of development with the composite spoke body itself, we have created a structure with many times the impact resistance of any steel spoke on the market today, all the while maintaining featherweight status. The finished spoke assembly consists of aerospace grade aluminum alloys, adhesives, graphene, and composite resin systems, all of which have been engineered from the ground up with weight, strength, fatigue resistance, and UV protection in mind.

Our lightweight hubs have been optimized and specifically matched to each rim profile to ensure proper angular alignment from the hub to the spoke hole at the rim. This means the spoke enters the rim at its natural angle, not where it is forced to. Our rims are designed effectively with matched drilling to accept the spokes at the proper angles. This means very specific rim hole drilling angles were chosen to alleviate stress risers and ease buildability. All of this comes together to create an extremely lightweight, durable, and reliable composite wheel system.
