Under the OSI model, the application layer, Layer 7, performs common application services for the application processes; the network layer, Layer 3, solves the problem of getting packets from one place to another across a network. The SSL protocol is quite unusual, as it doesn't just operate at one layer.

I hoped that over the years the price of the Rohloff hubs will drop, but they are still very expensive. If I look at the bikes in your recommendation list, when a bike is upgraded with a Rohloff, it costs 1000 Euro more. I have a Shimano 8 speed internal hub on one of my bikes, and on many hills I have to get off.he three axle plates available with Rohloff hubs are: 1  OEM plate (for frames with Rohloff dropouts); 2  OEM2 plate (for frames which have disc brake mounts or a support bolt); and. 3  Standard plate (or Torque Arm plate, for bikes which require the use of a torque arm).
