eeWings All-Road can be mounted on any modern road bike bottom bracket standard. The cranks use a 30mm spindle, so you just need to make sure the bottom bracket that corresponds with your frame is for 30mm spindle. We make Cane Creek bottom brackets that allow eeWings All-Road to be fitted to the following: 68mm threaded (BSA & T47 external), 86.5mm threaded (T47internal), 68mm press-fit (BB30 & PF30), and 86.5mm press-fit (PF41).
