The 1993 GT Tech Shop Catalog is a frame and components document rather than a full consumer catalogue — a focused, technical publication aimed squarely at dealers and serious riders who wanted to go deep on what GT was actually building.

At the sharp end of the lineup sits the Xizang LE, handbuilt in the USA from 3/2.5 titanium — a material with a strength-to-weight ratio almost twice that of steel — and race tested by the full Team GT roster including Rishi Grewal, Hans Rey, Jimmy Kight, Juliana Furtado, Chantal Daucourt, Gerhard Zadrobilek, Susan DiBiase, and Jimi Killen. Below it, the Zaskar LE brings 6061 T-6 heat treated aluminum with a ball burnished finish — a process GT describe as a mild form of shot-peening, extending surface durability by 300% over traditional hand polishing. Completing the frame trio, the Psyclone is GT’s premiere fillet brazed chromoly offering, handcrafted in the USA from True Temper GTX heat treated tubing and finished in lustrous DuPont Imron paint, with a notably clever detail: top tube cable routing hidden completely inside a groove on the underside of the tube.

The headline engineering story for 1993, however, is the RTS-1 — GT’s Rocker Tuned Suspension frameset, patent pending, combining a ball burnished 6061 T-6 aluminum front triangle with a chromoly rear triangle and a CNC machined aluminum rocker linking both to a fully adjustable USA-made Noleen coil-over shock. The Anti-Squat and Anti-Dive geometry built into the design represented a serious statement of intent from GT in the emerging full-suspension arena.

Rounding out the technical pages is a strong spread of GT house-brand components: the new Flip Flop-III Aheadset-compatible alloy stem, the Bologna Lite triple-butted chromoly fork, USA-made titanium axle bottom bracket, CNC machined 7075 aluminum cranks, titanium skewers with aluminum QR levers, and the Superlite alloy handlebar — demonstrating that GT’s ambitions extended well beyond the frame itself.
