ERider73-T17 BB with 4 Arm Spider/Claw

ERider torque sensor and crankset for 73mm wide bottom bracket shells with a 4 bolt 104mm spider. Unlike most other bottom bracket torque sensors, the ERider-T17N model has a cable exit from the side of the cartridge and does not require drilling a hole through the frame. This torque sensor accurately measures both left and right pedal torques and enables a very responsive PAS system. The 2 wire quadrature signal for the cadence sensing allows it to take advantage of the latest CA3 firmware which tracks back-pedal sensing for regenerative braking where applicable.

Includes 0 Q factor 170mm Cranks.

Chainrings are not included and would typically be moved over from the original crankset to this one during installation.

Please note that the most recent version of the 4 bolt 104mm spider no longer caters to 68mm BCD chainrings. If you specifically need this compatibility, please let us know as we have limited stock of the older version.

This sensor has an 18 pole single wire cadence sensor and a 1.5V - 3.5V output voltage that is proportional to crank torque with a scaling of 70 Nm/V. Includes 90cm long cable terminated with JST-SM connector, plug-and-play with V3 Cycle Analyst
