Highlights
De Propel Advanced SL Disc is ontworpen voor en getest door de snelste sprinters in het profpeloton. Hij biedt ultieme snelheid dankzij geïntegreerde aerodynamica. Deze fiets is ontworpen met behulp van de Giant AeroSystem Shaping-technologie waarbij elke framebuis en framehoek is geoptimaliseerd voor minimale luchtweerstand. Deze buizen hebben een afgekorte elliptische vorm en dat resulteert in een ultrastijf en superlicht frame. De schijfremtechnologie is geïntegreerd in de frameset met platte remklauwen en steekassen voor optimale wielstijfheid en remprestaties.

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 Composite SL 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.
RideSense
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 Bar/Stem
Composite integrated handlebar-and-stem unit improves aero performance with wind-tunnel shaped airfoil design and internal cable routing.
