Avid Yamaha no-slip drivhjul 1.75 Procross shaft

These drivers have antiratchet points as well as involute Points. We call these our Mseries drivers as the antiratchet points run in the clipped track windows and the involute bumps drive off of the four rows of rubber track bumps found in between the track windows. If you have a Yamaha and your driveshaft is prior to the 1.75 Procross shaft please refer to our Hex Shaft Drivers
