Build Quality and Performance
BST's GP TEK series represents the pinnacle of the brand's carbon wheel engineering. The rim is built from pre-preg carbon fibre — a manufacturing process that delivers a dense, void-free laminate with exceptional fatigue resistance under the repeated high-load cycling of track riding. The 6082 T6 aluminium hub is machined to exacting tolerances, ensuring perfect bearing seat geometry and reliable power transfer from the drivetrain. Every fastener is Titanium Grade 5, chosen for its superior tensile strength and corrosion resistance, while the carbon fibre inner spacer eliminates the weight associated with conventional metal components without compromising rigidity.
The wheel's load ratings are designed to cope with the demands of serious track riding: radial load 283 kg, static load 551 lbs / 250 kg, cornering load 720 Nm, and torsional load 1,043 Nm. These are not theoretical figures — they underpin the DOT E and JWL certifications that confirm the GP TEK's suitability for competition and track use.
