Riding Experience

In the morning, as the first ray of sunshine falls on the cobblestone roads of the French town of Provence. I am already ready and ready to join my new partner – Giant Defy Advanced 0 2025. Embark on this unknown cycling journey together.

The starting point is located by the ancient lavender field. The air is filled with a faint lavender fragrance, which makes people feel relaxed and happy. With my command, the pedal under my feet began to turn. The lightness and agility of Giant Defy Advanced 0 are fully displayed in an instant. I walked along the winding country road, flanked by lush vineyards and olive groves. It feels like being immersed in a stunning oil painting.

Climbing

Soon, we encountered an uphill section. Although the slope is not steep, it is enough to test the performance of a bicycle. I took a deep breath and increased the intensity of my pedaling. To my surprise, the transmission system of Giant Defy Advanced 0 is exceptionally smooth. With just a gentle flick, you can easily handle different slopes. Even when going uphill, I can feel its strong power output. It seems like there is an invisible force pushing me forward.

As the altitude gradually increases, the scenery in front of us becomes more spectacular. The towering and magnificent Alps are fully visible, and the distant snow capped mountains shine brightly in the sunlight. I couldn’t help but stop and capture this unforgettable moment. When I set off again, I couldn’t wait to feel the speed and passion of going downhill.

Descending

The downhill section is like a winding dragon, weaving through the dense forest. I clenched the brake tightly and felt the excellent handling performance of Giant Defy Advanced 0. Whether it’s sharp turns or bumpy roads. It can maintain a stable body posture, giving me confidence to face every challenge. The sensitivity and precision of the braking system left a deep impression on me. Just a gentle pinch can quickly reduce the speed to a safe range.

While enjoying the speed and passion, I also didn’t forget to appreciate the scenery along the way. Passing through lush green pine forests and passing by ancient bridges. I feel like I have traveled through a tunnel of time and space, back to that era full of poetry and distance.

Comparison

Giant Defy Advanced 0 VS Giant TCR Advanced，Disc 1+ AR

Some drivers prefer the crisp and direct shifting sound of SRAM. Considering this, the TCR series also takes into account the needs of these drivers. We have selected the complete SRAM Rival eTAP 12 speed electronic shift system. Provide a pure wireless gear shifting experience.

Compared to other versions, this car does not use top-level components. This may affect the smoothness of gear shifting and also lead to an overall increase in weight.

Giant Defy Advanced 0 VS Giant TCR Advanced Disc 1、Pro Compact

It uses high-value 105 components. Do not use the matching 105 sprocket, instead choose the more affordable Praxis sprocket. This further improves the cost-effectiveness of bicycles. It is very suitable for riders who want to upgrade in the future without feeling guilty about spending too much on the wheelset.

The disadvantage is obvious, as this is a road vehicle with aluminum wheels. If you are not planning to replace the wheels, heavy wheels may not provide the best riding experience.

Giant Defy Advanced 0 VS Giant TCR Advanced Pro，Disc 0 AR

The Giant TCR Advanced Pro Disc 0 AR is a highly anticipated product in the road bicycle market in 2023. This bicycle is equipped with top-notch components, which will leave a deep impression on even the most experienced riders. The Sram Force eTap electronic transmission kit is an excellent feature that only a few riders have the opportunity to experience. This kit provides incredible smoothness and precise shifting, making the overall ride more enjoyable and efficient.

Another impressive feature of Giant TCR Advanced Pro Disc 0 AR is the power meter. This is usually not visible within the same price range as this bicycle. For serious riders who want to track their performance and improve their training, this additional feature is a great tool.

Giant Defy Advanced 0 VS Giant TCR Advanced SL，Disc 1 AXS

The Giant TCR Advanced SL Disc 1 AXS is a top-notch comprehensive road vehicle. Even the most discerning rider will surely be impressed by it. This bicycle is equipped with high specification components, including the Sram Force eTap electronic transmission kit. This is an excellent feature, but not all riders are accustomed to the feeling of Sram shifting gears. In addition, the integrated seat bar is a unique and impressive feature. It not only looks very professional, but also significantly reduces weight and resistance. This feature enhances the overall riding experience, making cycling faster and more efficient.

Another potential drawback of the Giant TCR Advanced SL Disc 1 AXS is that it is difficult to adjust the length of the integrated seat rod arbitrarily. For riders who need to frequently adjust the saddle height, this may be a problem. Because they need to remove the entire seat pole in order to make any changes. In addition, the unique design of the integrated seat rod may make it more difficult to find replacement parts or accessories.
