Specifications

Upgrade your road bike's shifting performance with the microSHIFT R8 Rear Derailleur - a versatile, durable, and high-performance component compatible with 8- and 9-speed Shimano road shifters. Designed to deliver precise, reliable gear changes, this short cage derailleur is perfect for riders seeking smooth operation combined with a sleek black finish for a modern aesthetic.

Materials & Durability:

Constructed with a combination of high-quality composite and steel parts, the microSHIFT R8 rear derailleur offers excellent durability while maintaining a lightweight profile, weighing only 225 grams. The steel pulley cage enhances longevity, ensuring consistent performance ride after ride, making it ideal for daily commuting, endurance riding, or spirited road cycling.

Performance & Engineering:

Engineered to seamlessly work with Shimano-compatible road shifters, the R8 derailleur provides smooth, accurate shifting across an 8- or 9-speed drivetrain with a maximum sprocket size of 28T. Its short cage design optimizes chain tension for double chainring setups with 28T cogs, delivering crisp, confident gear shifts even under demanding riding conditions.

Components & Technology:

Equipped with steel pulleys for added durability and a robust cage, the R8 derailleur ensures consistent chain control and minimal derailleur wear. Its precise construction supports a chain wrap capacity of up to 33 teeth, accommodating most typical road gearings and ensuring broad compatibility with your drivetrain setup.

Style & Use Case:

Featuring a sleek black finish, the microSHIFT R8 rear derailleur complements any road bike aesthetic. Its compact, short cage design is perfect for double chainring configurations, making it suitable for versatile road cycling, commuting, and training rides where reliable shifting performance and style matter.

Innovative & Differentiating Features:

While compatible with 7 to 10-speed Shimano road shifters, the R8's blend of composite and steel components achieves a balanced compromise between weight and durability. Please note that this derailleur is not compatible with Shimano Tiagra 4700 systems, ensuring optimal performance within its specified ecosystem.

Upgrade your bike's shifting system with confidence - choose the microSHIFT R8 Rear Derailleur for dependable, precise, and stylish gear changing on every ride.
