OPM - Hub Drive System

Original Pawl Mega is GW’s Updated pawl driven system.

The OPM system has the same basic configuration as the OP system, Updated large Mega axle; has been increased from 15 to 17mm to provide significantly more strength and stiffness. By using this hub with a standard 12mm thru axle, the system is able to handle high torque loads on modern mountain bikes. It is also well suited for use on e-mountain bikes.

Thanks to the increased strength and stiffness of this hub, bearing longevity is increased so this hub enjoys lower service requirements. GW uses standard sized bearings so finding replacements is quick and easy.

We expect that these hubs will be used in less than ideal conditions, so the engineers paid careful attention to the seal design. Our Patent Pending Flex Seal; Prevent water and dust entering to the engagement chamber without added friction. Also allow rider to service the hub regularly without damaging the function.
