+The Shimano 8-speed is very similar to the 4-speed, but has a preliminary stage which either operates at unity ratio or gears down, doubling the number of speeds. This hub’s sequence of ratios is rather uneven; the steps from first to second and fifth to sixth are wider than the others, due probably to the difficulty of achieving a ratio near unity with a single stage. Efficiency is highest in the fifth gear, which is unity ratio.
