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.

Estimated Delivery & Collection Dates

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

2025 Giant Defy Advanced SL 1: The Ultimate Endurance Road Bike

Go long. Go fast. The 2025 Giant Defy Advanced SL 1 is superlight and silky smooth, reclaiming its title as the pinnacle of endurance road bikes. Perfect for sportives or gran fondos, this flagship series is designed for those epic rides circled on your calendar.

Key Performance Factors:

Functional Simplicity:Free of cumbersome gimmicks, the frameset is one of the lightest in its category. It offers a perfect balance of high-performance reactivity and all-day comfort, embodying a “less is more” philosophy for modern endurance road riding.
Engineered Compliance:The Advanced SL-grade composite frame and fork are specifically engineered for endurance road riding, delivering a smooth and efficient ride that minimizes fatigue on long rides. The new D-Fuse components work together to absorb road shocks and vibrations.
Total Control:The new Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for comfort and control on all-day rides. Wide, hookless carbon rims (22.4mm inner width) are optimized for high-volume tubeless tires (up to 38mm), and a 36mm rim depth offers stable, predictable handling in crosswinds.

Experience the ultimate in endurance road cycling with the 2025 Giant Defy Advanced SL 1, designed to keep you comfortable and in control on every ride.
