Bicycle stem and bicycle provided with bicycle stem

A bicycle stem comprising:

• a torque sensor that is more deformable by a torque about an X axis than by a torque about a Y axis or a torque about a Z axis when an identical torque is applied respectively about the X, Y, and Z axes, which are mutually orthogonal, to detect the torque about the X axis when a force is input from a handlebar or a steering column;
• a first stem including a handlebar connector connected to the handlebar and a first torque sensor connector connected to the torque sensor;
• and
• a second stem including a steering column connector connected to the steering column and a second torque sensor connector connected to the torque sensor;
• wherein
• the first stem and the second stem are configured such that the handlebar connector is positioned farther forward than the steering column and such that, when an identical torque about the X axis is applied, the first stem and the second stem are less deformable than the torque sensor.
