ERider73-T17 BB with 4 Arm Spider

ERider torque sensor and crankset for 73mm wide bottom bracket shells with a 4 bolt 104mm spider, compatible with most triple chainrings found on mountain bikes. 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 Miranda Cranks.

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

This sensor has an 18 pole 2 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

NOTE: Certain ERider setups are succeptible to electrical noise from the controller causing intermittent cutout behavior. This can be solved by grounding the bicycle frame.
