ERider73-T17 BB with 5 Arm Spider/Claw

The ERider-T17N is a bottom-bracket torque sensor and crankset for 73mm shells, here with a 5-bolt 130mm spider — compatible with most MTB triple chainrings. Its cable exits the side of the cartridge, so there's no drilling through your frame. It measures both left and right pedal torque for a smooth, responsive PAS, with quadrature cadence for CA3 back-pedal regen where applicable.
