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. **
