But Shimano doesn't use a ratchet. You can see here youtu.be/0j7p1DP2R5Y?t=735 that they're not pawls. Also, if Shimano did use a ratchet, without removing the cover we'd hear the clicking sound as the arm returns. They're likely dodging each other's IPs (and patents). I'm curious how SRAM does it. The SRAM clutch release button suggests it's yet a distinct system. | |
