Review ACE Derailer Rear 2x9 7700 Dura Crankset

The RD-7700 Ace Derailleur is a premium rear derailleur from Shimano, renowned for its exceptional performance and reliability. This 2x9 derailleur is part of Shimano's 7700 series, also known as Dura-Ace, which is their highest-end groupset.

The RD-7700 Ace Derailleur is designed to deliver smooth and precise shifts, even under heavy load or in demanding conditions. It features a lightweight yet robust construction, with a sleek and aerodynamic profile that reduces wind resistance and enhances overall bike performance. The derailleur uses a Shadow RD design, which helps to minimize chain slap and improve the aesthetic appeal of the bike.

The derailleur's adjustment mechanisms are easily accessible and intuitive to use, allowing for quick and accurate tuning to ensure optimal gear shifting. It is compatible with 2x9 drivetrains, making it a versatile choice for a wide range of cycling applications.

The derailleur works seamlessly with Shimano's Dura-Ace 7700 crankset, the FC-7700. This crankset is renowned for its stiffness, power transfer efficiency, and lightweight construction, making it an ideal choice for competitive cyclists and serious enthusiasts. The FC-7700 crankset uses Hollowtech II technology, which reduces weight while maintaining strength and rigidity.

In summary, the RD-7700 Ace Derailleur and FC-7700 Dura-Ace Crankset are a formidable pairing for any serious cyclist. They offer exceptional performance, precision, and reliability, making them a worthy investment for anyone looking to elevate their cycling experience.

1. High-quality components: Shimano 7700 Dura-Ace is a renowned brand known for its durability and performance. The derailleur and crankset are made with premium materials, ensuring smooth shifting and efficient power transfer.

2. Wide gear range: The 2x9 configuration provides a wide range of gears, making it suitable for various terrains and riding styles. This is particularly beneficial for climbers and riders who prefer a lower gear for steep hills or those who enjoy riding on flats and want a higher gear for speed.

3. Lightweight: The RD-7700 Ace Derailleur and 7700 Dura-Ace Crankset are built with lightweight materials, reducing the overall weight of the bike, improving its acceleration and maneuverability.

4. Precise shifting: Shimano's Synchro-Shift technology allows for smooth and accurate shifting between the front and rear gears, ensuring a seamless riding experience.

5. Aesthetics: Shimano Dura-Ace components are known for their sleek and elegant design, which can enhance the aesthetic appeal of your bike.

1. High price: Shimano Dura-Ace components are generally more expensive than their counterparts from other manufacturers. This might not be an affordable option for all cyclists.

2. Limited compatibility: The RD-7700 Ace Derailleur and 7700 Dura-Ace Crankset are specific to Shimano drivetrains, meaning they may not be compatible with other brands' components or frames.

3. Maintenance requirements: High-end components like Shimano Dura-Ace require more frequent maintenance to ensure they continue to perform optimally. This could be an added expense over time.

The Shimano RD-7700 Ace Derailleur, 2x9, and 7700 Dura-Ace Crankset are high-quality components that deliver excellent performance and durability. They are suitable for cyclists who prioritize precision, smooth shifting, and lightweight components, even if they come with a higher price tag and maintenance requirements. If you are looking for a premium drivetrain that can enhance your riding experience, the Shimano 7700 Dura-Ace components might be worth the investment. However, if you are on a budget or prefer a more universal drivetrain, you might want to consider other options.

Details:

Yes, it has some wear marks on it, but it is still in good working order. It was pulled from a working bike and cleaned up.
