Introducing the Nova Ride Aero and oversized derailleur cage, designed for Shimano Ultegra and Dura-Ace 12-speed derailleurs. Aerodynamic structure optimised by Nova Ride using software and wind tunnel tests.

Redefine aerodynamics.

• Drag reduction with emphasis on frontal impact optimization, as well as tailwind smoothing and control through its unique aircraft wing design (closed front and rear).

Structure optimization.

• Adding material over the standard version, without adding as much weight, required us to optimize the thickness of our ultra-light carbon fiber plates by 33% in key areas without compromising durability.

Performance without maintenance.

• Our fully ceramic dry bearings provide free rotation, less friction and grease-free bearings. The friction of ceramic balls against ceramic retaining cage extends the life of the bearings with less wear.

Optimization is the key.

• Months of development and feedback have allowed us to create our most efficient product to date. Its raw design reflects our priority: efficiency above all.

Features

• Materials: Two ultra-light and strong 3k carbon fiber plates, braided and custom machined. Two 7075 aluminum machined pulleys for increased durability. Two fully ceramic dry bearings for minimal friction and maintenance.
• Compatibility: Ultegra RD-8150, Dura Ace RD-9250 12-speed derailleurs.
• Weight: 113g.
• Maximum cassette size: We recommend a cassette with a maximum of 34 teeth for optimal adjustment and shifting.
• Chain Length: For optimum performance, replace your chain. We strongly recommend adding 2-4 additional links.
