More tire. More control. Built for speed.

The GGA 44 uses a 30 mm internal width to accommodate higher-volume gravel tires and support a broad tire platform. That geometry is intended to help riders access traction and side-knob support through rough corners and unpredictable terrain. It is a purpose-built choice for racers who want confidence from their tire setup.

Wide-rim support for confident cornering

With a 44 mm rim depth and an ultra-wide profile, the GGA 44 is designed around airflow management with larger gravel tires. Gulo lists an aero-optimized tire range of 38–45 mm, distinct from its broader fitment recommendation. That gives speed-focused riders a clear design target while leaving room for wider rubber when conditions demand.

Aero thinking for wide gravel tires

The GGA 44’s published semi-hooked construction includes a 4 mm rim lip intended to help resist pinch-flat impacts. Paired with G-Spoke braided composite spokes that help reduce transmitted vibration, the wheelset is designed to remain composed when racing surfaces turn harsh. It brings technical confidence to a performance-oriented gravel build.

Protection and composure on rough courses

The difference is in the G-Spoke.

Traditional wheel construction isn't the only way forward.

At the heart of all Gulo Wheels are G-Spoke braided composite spokes — engineered to combine vibration absorption, lateral stiffness, and impact strength in one distinctive wheel system.

Each spoke features a proprietary braided composite construction with titanium ends. Paired with carbon rims selected to complement the G-Spoke's performance, the result is a complete wheel engineered to work together.

The ultra-wide aero gravel specialist

Choose the GGA 44 for wide-tire gravel racing and a rim shaped around aero performance with larger tires. The GGA 38 has a narrower 25 mm internal rim and 38 mm depth for more general gravel aero use; the GGA SL has a shallow 23 mm profile and prioritizes minimum weight and climbing response.
