Use a 12x142 thru-axle in your Occam
The Concentric 9-12 dropout system on the Occam allows the use of a standard quick release rear hub or the 12x142mm thru-axle type. The thru-axle option adds stiffness to the rear suspension, allowing the wheel to track more precise lines through tight, technical terrain. And to be honest with you, wheel removal with the thru-axle is just as quick and easy as it is with the quick release configuration.
This is a RockShox Maxle Lite. It will not work for the Rallon; it is too long. The total length is 182mm. This axle is compatible with the Occam 29 and Occam 26 and allows you to run typical 12x142mm rear hubs. It must be used in conjunction with the 12x142mm Occam Dropout Set (sold separately).
