# How to shift the SRAM 3-speed hub

**Posted**: 2000-07-10




By: Bike Friday staff member Wolf Moritz




**Symptoms**


I'm having difficulty getting the three-speed hub to shift. (This refers to the SRAM 3x7 hub, formerly the SACHS 3x7 hub.)
**Solutions**



 
- Shifting is simple, but may take a while to get used to. While pedaling, move your left shifter one stop at a time to find the gear you want. There is an underdrive and an overdrive along with the middle direct drive to choose from.
 
- The hub will not shift under full pedal pressure. Shift the hub while pedaling, but back off on the pedal pressure a bit. On hills, pedal a little harder to gain some momentum, then ease off of the pedal pressure while shifting. It may sound complex, but shifting becomes second-nature rapidly.

Tip: *Try to anticipate hills by down-shifting in advance so you don't stall on a hill. You can shift back up again into the best gear for you while climbing.*
 
- Don't worry about a specific shifting sequence. Just ride in whatever gear "feels" right. Cross chaining is not a concern here!


 
**Additional Info**


 

 
- The hub will shift while coasting.
 
- The hub can be shifted at a standstill by pedaling backwards!
 
- It is normal for the hub to make a quiet clicking noise when riding. There are two sets of pawls inside.
 
- For your information, the gear ratios: under drive, 73%; middle range, 100% (1:1); overdrive, 136%.
