I think my bottom bracket is broken. The crank-set wobbles when I try to push it laterally. From what I understand, the bottom bracket is a Shimano BB-LP26, 118 mm spindle BB Shell Width 68mm English. I searched this up and cannot find a replacement. Also, does anyone know the torque specs for the bottom bracket screws and crank screw? What kind of taper is the Shimano BB-LP26 using?
