Fast feels better when smooth comes with it.

At 52 mm deep, the GRD 52 has the most pronounced aerodynamic profile in Gulo’s current road range. It is designed for riders who spend long stretches pushing the pace and want a wheel that feels eager to hold speed. The lightweight listed build keeps the focus on acceleration as well as aero intent.

A deep rim built to carry speed

Aero speed means little if rough pavement leaves a rider worn down. G-Spoke braided composite spokes are designed to absorb more vibration than steel spokes while maintaining lateral responsiveness. On the GRD 52, that translates into a performance story centered on comfort and control during fast training rides and long road events.

Less chatter over long road miles

Deep-section wheels can suggest a one-dimensional focus, but the GRD 52 is also notably light in its listed Gulo ETI configuration. That gives climbing-oriented riders a reason to consider its aerodynamic design rather than defaulting to a shallower rim. The result is a road-first wheel built for varied elevation and speed.

A road wheel that still likes to climb

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 aero-first road choice

Choose the GRD 52 when sustained road speed and a deeper aerodynamic profile matter most. Its 52 mm rim contrasts with the GRD 36’s shallower, all-round 36 mm design, while the low-profile GGX SL emphasizes mixed-surface versatility and nimble climbing. The GRD 52 is the road lineup’s clearest choice for aero-focused riding.
