  • Direct Drive. In top gear the transmission operates as a direct drive, sending engine input directly to the main shaft, eliminating parasitic gear mesh losses of power and fuel efficiency.
  • Oil Pump. An oil pump, powered by the countershaft, delivers oil directly to the gears. This is more precise and efficient than bathing all of the gears in oil.
Would these two points imply that in top gear not only are parasitic gear losses eliminated, but also losses from the oil pump?

Ah, I remember when a 10-speed was THE bike. Then came 18-speed mountain bikes, 21-speeds, 24, 27, and then I got lost
