We understand that it is hard to stop in time, sometimes we want to replace the seat immediately. Why is that? Is it even possible to make an individual perfect bicycle saddle?

Mechanical doping and average speed

Mechanical doping or technological doping  or tehno-doping this is related to devices for improve athletic performance. In cycling problem has become so serious that before each race bike scanned, judges search for hidden electric motor. I hope that in this case the developments of mechanical doping may well be used officially, if replace the battery by capasitor. This can give the with skillful management a significant increase of average speed.
