Description
The black Miranda spider is an aluminum 4-arm adapter for Shimano Steps motors like the E6100, with a BCD of 104mm and a chainline of 47.5mm. With the spider, you mount a separate chainring onto the motor shaft, so that when worn out you only replace the chainring. The aluminum keeps the weight low without sacrificing strength. The 47.5mm chainline is the standard size for many city and trekking e-bikes.
Why choose this product?
● Light aluminum: A sturdy spider without unnecessary weight.
● BCD 104mm: Compatible with many common 4-hole chain blades.
● Before purchasing: Check the motor type and the chainline of your e-bike.
