These are groundbreaking chainrings for e-bikes. It is known that normal OEM steel or aluminum chainrings last on average 3-6 months on an e-bike. Once worn out, there is a need to replace the chain and cassette due to excessive wear. The absoluteBLACK chainrings are about 5 times harder and reach a hardness of over1300 HV. This means that the Super Steel chainrings outlast conventional chainrings by 5 to 10 times, saving 2-4 cassette replacements.Due to several possible combinations of chainrings and spiders, we offer chainrings and spiders+pins separately to minimize the SKU count.
WHY YOU NEED A SUPER STEEL CHAINRING FOR E-BIKE
The drivetrain of an e-bike is subject to increased load and torque compared to conventional bikes due to the electric motor. This increased load causes accelerated wear of all drivetrain components and especially the chainring.
All OE (original equipment) chainrings currently supplied with E-bikes are made from mild steel, which is softer than steel used in chains. Due to the softness of this material, the teeth of the chainrings are 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 influence on the rest of the components. As chainring specialists, we know that increasing the hardness of the chainring can significantly reduce the wear rate of the entire drivetrain. That's why we developed the e-bike-specific, extremely durable Super Steel chainrings!
HOW TO CHOOSE THE RIGHT E-BIKE CHAINRING ASSEMBLY:
choose your chainring spider (inner ring)
Depending on the mid-motor your e-bike uses, first choose the correct mounting interface (Shimano, Specialized, etc.) and then choose the correct offset if required (Boost 53/52.5mm or Non-Boost 50mm). finally, choose the color of the spider and add it to the shopping cart.choose the tooth profile of the Super Steel chainring
choose between the 10/11/12 speed or Shimano 12-speed HG+ versions, depending on the chain used on your E-bike. choose the size of the Super Steel chainring
finally choose the size (number of teeth) of the chainring then the combination is complete

OXIDATION OF SUPER STEEL RING
Due to the material used and the manufacturing processes, surface oxidation (rust) may occur sporadically on the teeth of the chainring. It has no effect on the structural integrity or performance of the chainring and can be easily rubbed off. As a preventive measure, we recommend spraying the steel part of the chainring with a silicone spray or rubbing it with chain oil from time to time.
