T2 torque sensing bottom bracket
The T2 torque sensing bottom bracket is not a currently supported part. It appeared on the first batch of torque sensing eZee bikes, including a very small number of Primeros and Sprints. The T2 system has since been superceded by the T4 system.
At first the two types look quite similar. You can know you have a T4 bottom bracket if the cable exits from the side of the bottom bracket, as opposed to the middle (through a hole in the frame).
If you have a T2 eZee bike that requires a new bottom bracket, you can order this bottom bracket. Another option is to speak to your place of purchase about installing a T4 system. This requires not just a new T4 bottom bracket, but also a T4 crankset and reprogramming of the firmware.
