If 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.
Developed and proven by the fastest sprinters on the CCC Team WorldTour squad, the Propel Advanced SL Disc delivers ultimate speed through integrated aerodynamics. It’s engineered with Giant’s AeroSystem Shaping technology, which means every tube shape and angle is optimised for minimal drag. These tubes feature a “truncated ellipse” shape, which also result in a frame that is ultra-stiff and superlight. Disc-brake technology is integrated into the frameset with flat-mount calipers and thru-axles for optimal wheel stiffness and braking performance. For pro-level road performance and the ultimate aero advantage, the new Propel Advanced SL Disc puts you way ahead of the pack.
KEY PERFORMANCE FACTORS
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimises aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit produce the best overall aero performance.
Integrated disc brakes deliver powerful stopping power and modulation for added control in variable weather. Thru-axles boost stiffness and improve overall handling and an integrated WheelSystem with a 65mm rear rim and 42mm front rim optimizes aerodynamics and control.
Advanced SL-grade carbon composite frameset features Giant’s highest performance materials and manufacturing processes for optimised stiffness and the lowest weight in its category.

Delivery of Bikes
We ship all our bikes free of charge within the United Kingdom (excl. Jersey and the Channel Islands at this time) and all our bikes come pre-assembled with just a few tweaks required (Please see our Bike Build Instruction page for details of assembly required).
All our bikes undergo a safety check before being re-boxed for shipping which can during busy periods take a little longer to complete so whilst we aim to ship all our bikes within two working days of the order please allow for additional time for this process.
All our consignments irrespective of the carrier require a signature upon delivery, deliveries are typically made between 08:00 and 18:00 so please bare this in mind when choosing a delivery address.
We do try when possible to reuse packaging from our own suppliers in order to send purchased items to our customers, we ask if the packaging is still in good condition after you've received your goods then please try to use it again or recycle if not possible.
