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.\u003c\/p\u003e\n\u003cp\u003eIncludes 0 Q factor 170mm Cranks.\u003c\/p\u003e\n\u003cp\u003eChainrings are not included and would typically be moved over from the original crankset to this one during installation.\u003c\/p\u003e\n\u003cp\u003ePlease 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.\u003c\/p\u003e\n\u003cp\u003eThis 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\u003c\/p\u003e","brand":"Melbourne Powered Electric Bikes","offers":[{"title":"73mm","offer_id":49114873037035,"sku":"69007594","price":289.95,"currency_code":"AUD","in_stock":true},{"title":"83mm","offer_id":49114873069803,"sku":"69009606","price":289.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/5190\/7515\/files\/erider73qdims.jpg?v=1785138256","url":"https:\/\/melbournepowered.com.au\/products\/grin-erider73-t17-bb-with-4-arm-spiderclaw","provider":"Melbourne Powered","version":"1.0","type":"link"}
