Propel Advanced SL

PROPEL ADVANCED SL

Sprint finishes. Solo attacks. Breakaways. Proven through third-party wind-tunnel tests to be more aerodynamic from every yaw angle tested when compared to other leading aero road bikes, the Propel Advanced SL sets a new standard. Tests also showed that, at 40 kph, the Propel Advanced SL saves 12-36 seconds over 40 kilometers. Add in its class-leading light weight and superior ride quality, and the result is clear. Propel Advanced SL is faster from every angle.

Tech Highlights

Show Highlights

1

Integrated Seatpost

As the pioneer of the integrated seatpost, Giant continues to improve its original design with lighter weight (approximately 45 grams of weight savings, compared to a standard composite seatpost), improved aerodynamics and an even greater “tuned” forgiving ride feel.

2

Fusion Process

Advanced SL toptubes are “grafted” to the seattube using filament winding and co-molding. This complex process involves hand weaving the two tubes together, then re-molding the area under heat and high pressure to unify the junction - resulting in a lighter, stronger junction than with traditional molding.

3

Continuous Fiber Technology

This manufacturing process allows Giant to construct the front triangle of Advanced SL bicycles with larger -and therefore fewer- sections of composite material. With fewer pieces and junctions, the frames are up to 100 grams lighter and significantly stronger.

4

Contact SLR Aero Integrated Bar/Stem

An oversized box-section stem, designed for torsional stiffness and tuned for vertical compliance, is seamlessly integrated into a full carbon handlebar. The aero handlebar top profile maximizes aerodynamic performance.

5

OverDrive 2

Giant’s innovative oversized fork steerer-tube design increases front-end stiffness and enhances steering performance. The tapered steerer and oversized bearings (1 1/4-inch top, 1 1/2-inch bottom) boost torsional steering stiffness so you can sprint and corner with supreme precision.

6

SpeedControl SLR brake system

This proprietary braking system offers powerful, aerodynamic stopping power. A composite reverse-position front brake and seatstay-mounted rear brake are hidden from the wind. The system also features strategic trailing edges that further improve aerodynamics.

7

AeroSystem Shaping Technology

Data compiled from Computational Fluid Dynamics research and wind-tunnel tests was used to optimize the shape of every frameset tube and junction for overall system aerodynamics.

8

CNT Technology

Carbon Nanotube Technology refers to a microscopic polymer added to Giant’s custom-blended resin. Acting like miniature buttresses, CNT particles strengthen the layers of composite. Frames treated with CNT are 14 percent more impact resistant than those that aren’t.

9

PowerCore

A massively oversized bottom bracket/chainstay area features a fully integrated, 86mm-wide BB design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

RideSense

Giant’s all-new chainstay integrated, wireless data transmitter. The fully integrated, removable transmitter sends wheelspeed and cadence information directly to any ANT+ compatible computer.

Years of research, development and testing—in the wind tunnel and on the roads by Giant pro racers including sprinter Theo Bos—led to the all-new Propel Advanced SL, the world’s fastest aero road bike. Its wind-slicing new innovations include AeroSystem Shaping technology, the SpeedControl SLR brake system and Contact Aero handlebar. The Advanced SL-grade composite frame—with an OverDrive 2 steerer tube for stiff, precise steering and handling, and integrated seatpost for added aerodynamics and compliance—forms the backbone of a bike that has best-in-class light weight and unrivaled aero innovation.
