1903 Sunbeam 2 speed

120 1/8 bearings around the planetary gears and 30 more on the base of the sun gear and another 30 around the backing plate.

Being in an oil bath there was nothing to indicate 116 years of usage. I rode it back home from the home of the 95 year old owner.

The unit is completely modular and fits solely to the shaft. The extended shaft fits any English BB and the unit is free of any attachment to the frame. The selector has a cam that slides against a ramp that changes the gearing by 25%.
