hub dimension diagram
Unlike other dynamo hubs, this hub is rated for use in either rotation direction and can therefore be used on the left or right side of a trike. I entered the dimensions of the hub with it oriented as a right wheel (disc rotor to the left of the flanges). The wheel disassembled had an offset of 56.7mm from the registration flange to the centerline of the rim; recreating this offset exactly means you are NOT building a dishless wheel... The original wheel was not quite dishless either.
