Riding Experience

On a clear Sunday morning, I stepped onto my 2025 Giant TCR Advanced Pro 1 Di2 road bike. Preparing to participate in the classic event “Strada del Vino” held in Tuscany, Italy. The starting point is located in the picturesque town of Pienza. The finish line is the renowned Montepulciano wine region – Montalcino. This is not only a physical test, but also a deep exploration of the performance of TCR Advanced Pro 1 Di2.

Starting from Pienza, I rode along the winding country road. On both sides of the road are lush vineyards and medieval towns dotted among them. The carbon fiber frame of TCR Advanced Pro 1 Di2 is as light as air. Every time I step, I can feel the direct transmission of power, making it easy for me to cope with the undulating terrain. When I entered the first uphill section – the steep mountain road leading to San Gimignano. The advantages of Shimano Di2 electronic transmission system are fully demonstrated. I just need a gentle flick to quickly and accurately shift gears. Without any delay, it allows me to maintain the best cadence and easily conquer every slope.

Climbing

As the competition progressed, I sailed into the heart of Tuscany, where the terrain became even more varied. There are both steep uphill slopes and adrenaline pumping sharp downhill bends. On downhill roads, the handling of TCR Advanced Pro 1 Di2 is impressive. The rigidity of the frame and precise steering allow me to confidently cross corners at high speeds. The powerful disc brake system ensures smooth and powerful braking even during high-speed driving. Let me always maintain perfect control over speed.

Descending

As the competition drew to a close, I entered the final long downhill stretch towards Montalcino. This road, known locally as the ‘Road of Speed and Passion’, is winding and twisting. Along the way are endless olive groves and vineyards, with picturesque scenery. I increased the pedaling force, and the lightweight advantage of TCR Advanced Pro 1 Di2 once again became apparent. It seems to blend in with me, every step is transformed into a forward thrust.

In the end, I successfully reached the finish line of Montalcino. Surrounded by cheering spectators and friends who also love cycling. My TCR Advanced Pro 1 Di2 not only accompanied me through this challenging competition. It allowed me to experience unprecedented speed and passion while cycling.

Specifications

1. Frame and Structure

The frame is carefully crafted from advanced carbon fiber materials. This material not only has excellent lightweight characteristics, but also ensures the strength and rigidity of the frame. The excellent performance of carbon fiber enables the entire vehicle to reduce weight while maintaining its excellent performance. Still able to maintain sufficient stability and durability. The frame design is compact, so manufacturers only need to make a few frame sizes. Meet different heights and needs by adding longer uprights and seating poles. This design not only reduces production complexity, but also makes the frame more beautiful and coordinated. The interior of the frame is designed with cable wiring. Fix the cables neatly in the groove below the stand. This design not only enhances aesthetics, but also facilitates cable replacement and maintenance.

2. Variable speed and transmission

Equipped with Shimano’s Di2 electronic transmission system, which controls gear shifting through electronic signals. Achieved a precise, fast, and reliable shifting experience. Riders can quickly switch gears with just a gentle flick. Don’t worry about inaccurate or delayed gear changes. The large gear and rear shift also use Shimano’s high-performance components, perfectly matched with the Di2 electronic transmission system. Ensuring the stability and durability of the transmission system.

3. Braking system

The TCR Advanced Pro 1 Di2 is equipped with a powerful disc brake system. This braking method has higher braking performance and stability compared to traditional ring brakes. The disc brake system can provide smooth and powerful braking effect during high-speed driving. Ensure that riders can quickly stop in emergency situations. The brake clamp adopts the Ximano UT series. Has excellent braking performance and durability. The clamp is closely matched with the disc brake disc, ensuring the stability and reliability of the braking effect.

4. Tires and Wheel Sets

The tire clearance has been increased to 33 millimeters and a wide tire design has been adopted. This design can better filter high-frequency road noise. And eliminate the sharp edges of low-frequency roaring sounds, improving riding comfort. Meanwhile, wide tires can also provide better grip and stability. Especially more confident when turning. The wheelset adopts Giant SLR series carbon fiber wheelset. Has excellent lightweight characteristics and rigidity. Carbon fiber wheelsets can reduce the weight of the entire vehicle while improving riding efficiency and speed.

5. Aerodynamic Design

The TCR Advanced Pro 1 Di2 draws inspiration from the design of Giant Propel. Adopting a Kamm tail shaped tubular contour. This shape is considered to be the most effective in reducing drag, as it has a smaller surface area exposed to crosswinds compared to a complete teardrop shape. This design helps to improve cycling efficiency and reduce the physical exertion of riders. The rear fork of the frame is designed to be slender. Save power loss for the frame assembly. This design not only enhances aesthetics, but also further improves riding efficiency.

Comparison

Giant TCR Advanced Pro 1 Di2 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 TCR Advanced Pro 1 Di2 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 TCR Advanced Pro 1 Di2 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 TCR Advanced Pro 1 Di2 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.
