Bafang BBS01/02 104BCD Chain Ring Adaptor

thingiverse

104BCD Chain Ring Adaptor to suit the Bafang BBS01 and BBS02, I used a 32 tooth narrow wide chain ring, you can most likely go up to a 36 tooth and the chain guard should still keep the chain inside the lip. Has integrated chain guard to decrease complexity and to increase its strength. Please do not print in anything but high strength Nylon with Carbon Fibre. I used ePAHT-CF and I baked the finished part in the oven at 120 Degrees C for around 4hrs Also, use 8 walls, no infill and with 99+ layers, first layer set to concentric purely for looks, then each layer after that set to lines at make each one 45 degrees from the other, using this pattern: 45, 90, 135, 180, 225, 270, 315, 360.
