REAL GEARS
Real gears refer to the gear steps of a bicycle transmission that can be optimally used. In derailleur gears, the skewed running of the chain leads to significant losses of efficiency. In addition, when there are two or three front sprockets there will be redundant, i.e. equivalent, gears. A 3×10 derailleur transmission, for example, actually only offers 14 or 15 real gears from this perspective.
