First Ride: Industry Nine's New TR280 Carbon Wheelset
"You have one leading pawl that starts to take the load or force from pedaling, but because the pawls are phased close together and the tooth count is so high, as soon as you apply torque to the system, or pedal, a second, third, and fourth pawl will start to take some of the torque load and evenly distribute the load. It utilizes the inherent flex in the drive system to transfer the torque and ensure that a single pawl will never take the entire load. This is where Industry Nine claim that their system has an advantage over a traditional pawl system that can’t limit that flex - they say it limits and minimizes wear and tear on the system and provides a more consistent ride." source - https://www.pinkbike.com/news/review-industry-nines-690-point-engagement-hydra-hubs.html
