Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.

Propel Advanced SL Disc
Ultimate Speed
When speed is your obsession, this is your bike. You train, you put in the work, and this aero machine does the rest. Built to give you an edge when it really counts—on the attack, in the sprint, going all out—it delivers energy-saving efficiency and race-winning aero performance.
Factores Clave de Rendimiento
Aerodinámica Integrada
El AeroSystem Shaping, resultado de análisis CFD (Dinámica de Fluidos Computacional) y pruebas dinámicas en túnel de viento, mejoran el desempeño aerodinámico en cualquier angulo de incidencia del viento. Las formas de elipse trunco con perfil aero en los tubos y componentes Contact SLR Aero dan como resultado el mejor desempeño aerodinámico.
Control Total
Los frenos de disco integrados entregan gran potencia de frenado y modulación para mayor control en cualquier condición y clima. Ejes pasantes aumentan la rigidez y mejoran el manejo en general. Un sistema de ruedas integrado con un aro trasero de 65mm y 42mm delantero optimiza la aerodinámica y el control.
Eficiencia Sin Igual
El cuadro de Carbono grado Advanced SL se caracteriza por ser fabricado con materiales y procesos del más alto desempeño para mejorar la rigidez y ofrecer el menor peso en su categoría.
Aerosystem Shaping Technology
Vector Integrated Seatpost
Designed as a key performance factor in the overall frameset, the integrated seatpost saves up to 45 grams compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.
Advanced SL Composite Frame
Giant's Professional Grade carbon material is woven in our own composite factory using a proprietary resin formula and our most advanced engineering and construction methods including: Continuous Fiber Technology, CNT Technology and Fusion Process.
OverDrive 2
Giant’s most advanced steerer tube technology offers unprecedented steering precision. Oversized headset bearings (1 1/2” lower, 1 1/4” upper) and a tapered steerer tube produce superior front-end stiffness.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Internal Cable Routing
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
Disc-Brake Integration
The frame and fork are engineered specifically for flat-mount disc-brakes, including front and rear 12mm thru-axles for reliable braking performance in all weather and road conditions.
Contact SLR Bar/Stem
Composite integrated handlebar-and-stem unit improves aero performance with wind-tunnel shaped airfoil design and internal cable routing.
