If you take a little time to get to grips with it, you can find out whether your gears can be optimised.
Hub gears and derailleur gears all have the purpose of offering cyclists a variety of gears. What is important here is not only the gear range, i.e. the range of gears offered, but also how the gears are graded in relation to each other.
The advantage of a higher number of gears is that they can be stepped more finely, for example, with a constant ratio range. Or they can be set up wider overall with the same gradation. The gear range of a gear hub is predetermined by the design and cannot be subsequently changed.
However, the resulting gear range can be influenced by the choice of front chainring and rear sprocket (and the size of the rear wheel). If you choose your gears carefully, you can achieve a usable gear range even with a gear range of almost 700%.
