Many gears, a wide range from the lightest to the heaviest gear, the shift jumps as evenly and closely graded as possible. And the whole thing should be as light and durable as possible. This is roughly what the specifications for a bicycle gear system might look like. Today's answer: a chainring at the front, a huge cassette at the rear. In the case of Sram's Eagle drivetrain, this results in a range of 520 percent. 

Classified looks similar at first glance: The single chainring, the chain, the 12-speed shifter and the rear derailleur all come from the industry giants from the USA and Japan. However, the hub and cassette are innovative and proprietary: the hub features a two-stage planetary gear system that virtually doubles the gears on the in-house cassette with 11-40 teeth. As befits hub gears, you can shift gears while standing without pedaling. This can certainly be an advantage in mountain biking and tricky riding situations.

Classified has also eliminated a disadvantage of hub gears (aka poor shifting under load): up to 1000 watts on the crank, shifting is possible even under load, and at lightning speed, thanks to a wireless Bluetooth switch on the handlebars. Classified boasts a bandwidth of around 530 percent. And the mountain bike groupset should be available as a wheelset or with the individual Classified components from the end of May 2023.
