absoluteBLACK Shimano Steel 11/12 Speed E-Bike Chainring

The Ultimate, most durable, E-bike specific Super Steel chainring for 11-12sp chains. It is a well-known fact, that high power e-bike motors tend to wear out the drivetrain in a very short time. The accelerated wear always starts from the chainring. This is why we have developed "Super Steel" chainring that can potentially save you 2-3 expensive cassette replacements, thanks to its incredible durability. What we mean by "Super Steel" is premium steel, that has been cnc milled, not stamped, then heat treated and lastly, put through multiple highly specialized nitriding and carburizing surface treatments to achieve micro hardness of an impressive 1300HV. All this results in a chainring that is over 4 times harder than a standard, stamped steel OEM chainring. Compatible only with absoluteBLACK e-bike spiders. Spider sold separately.

WHY YOU NEED A SUPER STEEL CHAINRING FOR E-BIKE
The drivetrain of an e-bike is subject to increased stress and torque as compared to conventional bicycles, as a result of the electric motor. This increased stress causes accelerated wear on all drivetrain components and especially the chainring.

All OE (original equipment) chainrings which are currently supplied with e-bikes, are made of mild steel, which is softer than steel used in chains. Because of the softness of this material, the teeth of the chainrings get worn by the chain and deform quickly, which in turn increases the wear rate of the chain and ultimately the cassette. In a way it is a ‘symbiotic system’ where each component has an impact on the rest of the components. As chainring specialists, we know that increasing the hardness of the chainring can significantly reduce the rate of wear of the entire drivetrain. This is why we have created our e-bike specific, extremely hard wearing Super Steel chainrings!
