More details of the Extralite CyberRear SPD-3

The CyberRear comes with an external bearing preload system. The precise bearing setting ensures a low friction and no-play at the rim. The hub is equipped with drillngs for straight pull spokes - straight pull spokes increase the wheel stiffness under load and reduce lateral flex while increasing the disc braking torque transmission. 

Compared to the previous model the SPD-3 comes with a more equalized spoke camber on each side and can now handle higher spoke tensions. Furthermore it is not needed anymore to open the hub for wheel building or spoke replacement.

Please Note: CyberRear freewheel mechanisms are suitable for road and cyclocross use (not MTB). The minimum gear ratio is 1.00. Shorter ratios may result in high torque and damage freewheel mechanism.
