The ERider-T17N is a bottom-bracket torque sensor and crankset for 100mm shells, here with a 5-bolt 130mm spider for the wide chainrings on fat bikes that need wider bottom brackets. 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.
