The ERider-T17N is a bottom-bracket torque sensor and crankset for 68mm shells, here with a 5-bolt 130mm spider — a common size compatible with many triple chainring sets. 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.

Specs:

• Fits 68mm bottom-bracket shells · 5-bolt 130mm spider
• Includes 0 Q-factor 170mm crank arms (chainrings not included)
• Side cable exit — no frame drilling
• 18-pole, 2-wire cadence sensor
• 1.5–3.5V torque output, 70 Nm/V scaling
• 90cm cable, JST-SM connector — plug-and-play with the V3 Cycle Analyst

Note: some ERider setups can get intermittent cutout from controller noise, solved by grounding the frame.
