Trike front hub with dynamo and 90mm drum brake. Only to be used on right side of vehicle.
Because there is no single plane in which the rim must be centered, I have chosen to express the flange offsets symmetrically in the database. Adjust these to achieve any dish needed for your application, or build symmetrical about the flanges for equal spoke tension. If rebuilding for an existing application, take careful measurements of an existing wheel to replicate the rim location relative to where the hub mounts.
Contributor notes: "Axle is 12mm, protrudes 70mm from brake plate. Hub is approximately 70mm wide."
