{"product_id":"bb-erider100q-4b","title":"ERider100-T17 BB with 4 Arm Spider","description":"\u003cp\u003eThe ERider-T17N is a bottom-bracket torque sensor and crankset for 100mm shells (mostly fat bikes). 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.\u003c\/p\u003e\u003cp\u003eSpecs:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFits 100mm bottom-bracket shells (mostly fat bikes) · 4-bolt 104mm spider\u003c\/li\u003e\n\u003cli\u003eIncludes 0 Q-factor 170mm crank arms (chainrings not included)\u003c\/li\u003e\n\u003cli\u003eSide cable exit — no frame drilling\u003c\/li\u003e\n\u003cli\u003e18-pole, 2-wire cadence sensor\u003c\/li\u003e\n\u003cli\u003e1.5–3.5V torque output, 70 Nm\/V scaling\u003c\/li\u003e\n\u003cli\u003e90cm cable, JST-SM connector — plug-and-play with the V3 Cycle Analyst\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNote: the latest 4-bolt 104mm spider no longer fits 68mm BCD chainrings (limited older stock — ask us).
