Thanks to the different primary and gear wheels you now have an unprecedented freedom in the gradation of your transmission. So you can build a transmission with your desired gradations. From the closely stepped racing gearbox to the tourer gearbox for the shift muffle. Especially with the Smallframe transmissions, everything is possible due to the combinations of different gears, three different auxiliary shafts and the primary wheels.
