Reengineered with Giant’s AeroSystem Shaping technology, which means that every tube shape and angle is optimized for minimal drag with a new "truncated ellipse" shape, the Advanced SL-grade composite frame is ultra-stiff and superlight. And its new disc-brake technology is integrated with the frameset, including flat-mount calipers and thru-axles for optimal wheel stiffness and braking performance on the road. For pro-level road performance and the ultimate aero advantage, the new Propel Advanced SL Disc is way ahead of the pack. Here are the core technologies that set the Propel Advanced SL Disc apart from the competition.
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
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-Grade Composite
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.
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.
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.
Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.
Integrated Giant WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this composite SLR Aero WheelSystem features different rim depths front and rear to minimize drag without compromising stability. The rear has a 65mm rim for uncompromising aero performance and power transmission. The front has a shallower 42mm rim for added control in crosswinds. The wheels are integrated with Giant Gavia tubeless tires for added rolling efficiency and a reduced risk of flats.
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 Aero Bar/Stem
Composite integrated handlebar-and-stem unit improves aero performance with wind-tunnel shaped airfoil design and internal cable routing.
