Re: Grubee HD axle and BAND DRUM BRAKE
Sorry it's taken so long to get back with you. I honestly forgot about it.
The id of the sprocket hole is 2.5in.
The width of the axle with the brake and pedal sprocket from inside the bike frame to the other inside bike frame is 5in on mine. I didn't have to bend mine, but it is pretty difficult install without having a tool to help spread the frame a little.
