In 1912, the belt driven 499 cc (30.5 cu in) Multigear was released, using variable groove-depth pulleys to provide 21 forward gear ratios, with top gear as high as 2.75:1. (
The Zenith Gradua and 1907 FN 244 cc single used a similar system.)
In 1913, a 750 cc (46 cu in) Multigear was released.
In 1914, Cyril Pullin won the Isle of Man TT on a Rudge Multigear.
Together with the Zenith-Gradua this was one of the first continuously variable transmissions (CVT).

In 1923, Multigear production ended.
