GT Vengeance Frameset is a dedicated triathlon and time-trial platform with a design lineage that goes back further than most tri frames on the market. GT introduced the Vengeance as part of a trio of aero road bikes built around the same design philosophy as the brand's Superbike — the aggressively shaped aero platform that helped define what a serious TT bike looked like. Sold here as a frameset, it gives you the frame and fork as a foundation, leaving the drivetrain, cockpit, and wheels open to build around your own fit and target race distance. The frame is 6061-T6 aluminum, TIG-welded, and shaped around GT's signature aero tube profiles — most noticeably an oversized, wide down tube designed to smooth airflow and add stiffness where a triathlon frame needs it most, under hard, sustained pedaling effort in an aero position. That kind of pronounced tube shaping was distinctive even when GT introduced it, and it remains one of the more recognizable design details in the brand's history of aero-focused engineering. The Vengeance traces its design roots to GT's Superbike lineage, one of the more influential aero platforms in the brand's history, and riders who know GT's history tend to recognize the connection in how the tubes are shaped. It's a frame built specifically to hold a rider in a forward, aggressive position through the bike leg of a triathlon or the length of a time trial, rather than a road frame adapted after the fact with clip-on bars. Buying the Vengeance as a frameset makes sense for a triathlete or time-trial rider who already knows what they want in a build — someone who wants to spec their own drivetrain, base bar and extensions, and wheels rather than working around a pre-packaged component group. It's available here in a single Medium size in Blue, so fit is worth confirming carefully before ordering, but for a rider who lands in that size range, it's a direct path to a proper tri-specific aluminum platform without the cost of building from a full complete bike. At this price, the Vengeance is a straightforward way to get a genuine dedicated triathlon frame with real design pedigree behind it. It's a frame for a rider who wants distinctive, purpose-built tri geometry and is comfortable choosing and installing their own components around it.
