GB-75 Gearbox
Racquetball· GB-75
Updated on 10/03/2026
The GB-75 is Gearbox's entry-level composite, designed for recreational and club players who want to move on from aluminum racquets. It weighs 190 g unstrung and uses 60% graphite and 40% fiberglass, stiff enough for power and durability. The GB Power string pattern creates a dense sweet spot and loosens the edge strings to gain power, and the proportional frame design balances stability and maneuverability. It comes with 17-gauge monofilament string, a 3 5/8 in grip and vibration control.
