Overview

Gearbox identifies the GB-75 as a racquetball racquet and lists its material composition, unstrung weight, string, and grip size. Those details make the exact product easier to distinguish in a catalog.

Construction and context

Gearbox specifies 60% graphite and 40% fiberglass, along with a 17-gauge monofilament string. Published construction terms do not independently establish feel, power, or durability in use.

Who it may suit

This record can help a shopper narrowing products by a stated 190 g unstrung weight, material listing, or 3-5/8-inch grip size. It cannot determine fit or expected results for an individual player.

Specifications in context

60% Graphite, 40% Fiberglass
This is the manufacturer-published material composition and a comparison field, not an independent assessment of construction quality.
Gearbox 17g Monofilament
This identifies the listed string specification; it does not predict tension, longevity, or feel for every unit.

Tradeoffs and caveats

  • The listed weight applies before stringing.
  • Material percentages do not quantify on-court behavior.
  • Verify the exact retail configuration on Gearbox's current page before buying.
