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 Road Bike 2026 in Ultra Navy/Azure

Season:2026Sale

Brand:Giant

Code:9074025Ultra

The Giant Propel Advanced SL 1 is an aero-focused race machine built for sprinters, breakaways, and high-speed performance. Its Advanced SL-grade Composite frame with integrated seatpost, AeroSystem Shaping, and OverDrive Aero fork delivers outstanding stiffness-to-weight and aerodynamic efficiency. Equipped with Shimano Ultegra Di2 electronic shifting, a Giant Power Pro power meter, and CADEX 50mm Aero carbon wheels with tubeless-ready tyres, this bike is engineered for precision, speed, and race-winning performance on the road.

Integrated aerodynamics

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.

Easier adjustability

Cable routing through the stem and head tube makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position.

Race-winning efficiency

Advanced SL-grade composite frameset features Giant’s pro-level composite materials and manufacturing processes. The result is 150 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage.
