Smooth Torque Sensing Pedal Assist

Precision torque sensing performance at 104 cadence pulses per revolution; 1,000 torque samples per second. Colt’s incredibly smooth torque sensor knows how hard you’re pedalling down to the microsecond and matches it with proportionate power. Custom drop out design delivers whisper smooth torque sensor sensation at any assist level. In fact, you’ll swear it’s as smooth as a mid-drive motor. Gone are the days of simple cadence sensors!
