Designed by our French engineers directly in our design office, our carbon cage for rear derailleur is easy to mount, improves the transmission of your derailleur group and brings a touch of color to your bike.
Our cage is made with very high-end materials: Ultra-lightweight carbon fiber, 7075 aluminum alloy and fully ceramic sealed bearings that are designed to last over time.
Our aluminum rollers have no wear compared to standard plastic rollers. Our sealed bearings protected by aluminum covers allow a longer lifespan. We designed these treads so you don't have to worry about maintenance or technical issues.
We recommend equipping your bike with a new chain to go with your Nova cage. We recommend adding 3-5 links from your previous chain.
We recommend a cassette with no more than 32 teeth for optimal shifting.
