Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Giant Propel Advanced SL 1 Men’s Aero Road Bike – Lightweight Carbon Racing Bike

The Giant Propel Advanced SL 1 Men’s Road Bike is a pro-level aero road bike designed for sprinting, breakaways, solo attacks, and race-winning performance. Engineered with lightweight SL-grade composite technology, advanced aerodynamics, and adjustable fit, this Giant aero road bike delivers maximum speed, efficiency, and comfort for competitive and serious riders alike.

Integrated Aerodynamics

The Propel Advanced SL 1 features AeroSystem Shaping, refined through CFD analysis and wind-tunnel testing, to optimise aerodynamic performance at every yaw angle. Truncated ellipse airfoil tubes and the Contact SLR Aero cockpit reduce drag and boost efficiency, helping you gain an edge in every sprint, climb, or solo attack.

Easier Adjustability

Internal cable routing through the stem and head tube makes it simple to adjust or upgrade cockpit components, allowing riders to fine-tune fit, position, and performance quickly.

Race-Winning Efficiency

Built from Giant Advanced SL composite carbon, this frameset is light, stiff, and responsive, saving up to 150g over previous generations. The result is superior stiffness-to-weight ratio and efficient power transfer for XC, road racing, and long endurance rides.

Advanced SL Composite Technology

Professional-grade carbon fibre is woven and moulded in Giant’s composite factory to produce a lightweight, high-performance frame trusted by pro racers across disciplines.

OverDrive Aero & Integrated Seatpost

The D-shaped fork steerer tube with OverDrive Aero improves cable routing, aerodynamics, and serviceability, while the integrated seatpost reduces weight and enhances road compliance.

Tubeless System Ready

Experience fewer flats, greater traction, lower rolling resistance, and a smoother ride. The Giant Tubeless System ensures you can ride fast with confidence on race day or long training rides.

This Giant Propel Advanced SL 1 Men’s Aero Road Bike is the perfect choice for riders who demand lightweight carbon performance, aerodynamic efficiency, and race-ready handling on the road.
