Go long. Go fast. Superlight and silky smooth, the flagship series of the new Defy range is back to reclaim its title as the pinnacle of endurance road. It’s the perfect choice for the sportive or gran fondo that’s circled on your calendar.
With greater lateral stiffness and a superlight frame weight of 785g, this is the most efficient Defy ever. The composite frame layup targets smooth-riding performance for long, hard rides. The new D-Fuse SLR seatpost is now lighter and engineered with 40 percent added compliance. The Contact SLR D-Fuse handlebar, also new, features similar D-shaped tubing as the seatpost to absorb shocks and vibrations, plus an 8-degree flare for improved ergonomics and control. Component highlights include the new Contact SLR AeroLight stem with integrated cable routing. A CADEX 36 WheelSystem with superlight hookless carbon rims delivers snappy yet stable handling and superior tubeless tire performance.
Functional Simplicity
Free of cumbersome gimmickry, the frameset is one of the lightest in its category. With a perfect balance of high-performance reactivity and all-day comfort, it offers a “less is more” experience for modern endurance road riding.
Engineered Compliance
Advanced SL-grade composite frame and fork are specifically engineered for endurance road riding, delivering a smooth and efficient ride quality that minimizes fatigue on long rides. The new D-Fuse components work together to further absorb road shocks and vibrations.
Total Control
A 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.

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.
We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
