Gear Assy 1
Gear assy one (1) is shifted like 2nd gear. One sprocket rotation results in 0.774 planet carrier rotations (1-2).

Gear Assy 2
Gear assy two (2) is shifted like 7th gear. One planet carrier (1-2) rotation results in 1.467 joint ring gear (2) and sun gear (3) rotations .

Gear Assy 3
Ring gear (3) and sun gear (3) are coupled together, thus the stepped planet gears (3) cannot rotate. Gear assy (3) is therewith shifted 1:1 and transfers the rotation from gear assy (2) directly to the planet carrier (3).

One sprocket rotation results in:- 0.774 (Gear Assy 1) x 1.467 (Gear Assy 2) x 1 (Gear Assy 3) = 1.135 hub rotations.
