Absolute Black Road 110BCD 4-bolt 50T Black Oval Chainring

Brand:Absolute Black

Code:ROV50/4BK

 
The oval chainring movement across all cycling disciplines is growing rapidly, led by absoluteBLACK, the world leaders in this important product category.
 
 
However, not all oval chainrings share the same performance characteristics as absoluteBLACK. The 'clocking' (timing) and shape of the oval are the most crucial parts of any oval chainring design, and absoluteBLACK spent three years in design development. This has allowed them to perfect both timing and shape design elements - ensuring the ride quality of absoluteBLACK oval rings is superior to ovals from other brands.
 
 
Where most other brands retain the same timing (position of the crank arm relative to the oval) and shape of the oval across all their sizes - because it's cheaper and less time consuming. absoluteBLACK believe that each different size ring requires a bespoke, optimised, perfect pedalling solution.
 
 
Their longterm belief in oval rings and the development of their design has led absoluteBLACK to become the most commercially successful oval chainring product in the world. So keep in mind that not every oval chainring is equal to an absoluteBLACK.
