The SRAM internal gear hub may not shift into first gear due to a few possible reasons. One common reason could be that the cable tension is not properly adjusted, causing the hub to not engage with the first gear properly. Another reason could be that the hub needs to be cleaned and lubricated, as dirt or lack of lubrication can prevent smooth shifting. Additionally, there may be internal damage or wear to the hub's components that is preventing it from shifting into first gear. **

The Shimano S7 internal gear hub may not be working anymore due to a variety of reasons.

Internal energy is the total energy contained within a system, including the kinetic and potential energy of its particles. It is a measure of the system's microscopic energy, which can include the energy associated with the motion and interactions of its molecules. Changes in internal energy can occur through heat transfer or work done on or by the system. **

Internal bleeding refers to the loss of blood inside the body, rather than from a visible external injury. This can occur due to trauma, such as a car accident or a fall, or from medical conditions such as ulcers, ruptured blood vessels, or certain medications.
