Rear Derailleur | Novo Cicli

Rear Derailleur | Precision and Chain Control

The rear derailleur is the mechanical (or electronic) heart that manages chain tension and shifting speed. It's the most exposed and stressed component, responsible for sliding the chain between the sprockets with surgical precision. At Novo Cicli , we offer a range of derailleurs, from traditional mechanical systems to the latest wireless innovations, always ensuring maximum compatibility with your setup.

Types of Derailleurs: From Mechanical to Wireless

The market has evolved and with it the complexity of this component:

Electronic Derailleurs (Di2 and AXS): They represent the pinnacle of technology. Thanks to high-torque internal motors, the gear shift moves with consistent precision, eliminating cable stretch issues. They are the key components of our Complete Groups high-end.
Clutch Derailleurs: Essential for the gravel and mountain bike world. Systems like Shimano's Shadow RD+ or SRAM's Orbit stabilize the chain, preventing it from hitting the frame or falling off on the roughest terrain.
Short, Medium or Long Cage: The choice of cage length depends on the Sprocket Pack that you use. Our technicians will guide you in your choice to ensure that the derailleur can properly handle the total capacity of your drivetrain.

The Heart of Our Used Bikes

At Novo Cicli, the rear derailleur is the first element that our mechanics inspect on incoming used bikes :

Dropout Alignment: We use precision instruments to ensure the derailleur hanger is perfectly straight; even a high-end derailleur will never function properly if the dropout is crooked.
Pulley Condition: We check the wear of the wheel teeth and the fluidity of the bearings. Often, an upgrade to the CeramicSpeed Ceramic Pulleys It can breathe new life into a used transmission, making it smoother than the original.
Total Refurbishment: Every used bike sold by Novo Cicli has a cleaned, lubricated, and adjusted derailleur to ensure shifting as if it were new.

Why Replace the Derailleur?

A rear derailleur should be replaced or upgraded when:

Gear Update: If you decide to run a cassette with larger sprockets for extreme climbs, you may need a derailleur with a longer cage.
Play Wear: Over time, the parallelogram pins can become loose, making shifting imprecise and noisy.
Impact Damage: Being protruding, it is subject to impacts; even a small deformation can compromise the synchrony with the crowns front.
