The ultimate e-bike chainring Spider was developed for specialized Brose motors with Boost 53mm chainline. Super light and durable design. The Spider is only compatible with absolutBLACK Super Steel chainrings. Spider comes with 5 titanium chainring bolts. Chainring sold separately.
These are groundbreaking chainrings for e-bikes. It is known that normal OEM steel or aluminum chainring lasts 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 over 1300 HV. This means that they outlast the normal chainring by 5 to 10 times and save 2-4 cassette changes. due to several possible combinations of chainrings and spiders, the chainrings and spiders (incl. bolts) are offered separately.
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 (Boost 53/52.5mm or Non-Boost 50mm) if required. 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
