After Shimano withdrew their Biopace chainrings from the market, any attempts to relaunch oval chainrings were often ridiculed. Nevertheless, they are still available, and brands such as Absolute Black are even successfully filling this niche. The truth of the "egg-shaped" chainring was explored in various tests during the last bike season.

The portfolio of the distribution company Rasant is on the move: The company is now supplying specialist retailers with products from Absolute Black. Absolute Black has made a name for itself since 2008 with innovative products such as 10-speed cassettes with 40 teeth and (oval) chainrings.
