We warmly recommend to precisely check all the operations involved for the assembling and the tuning process before setting your order.
You'll have to take the full responsibility on both hub-assembling and hub-tuning (see details on manual).
Alternatively consider CyberFront SL and CyberRear SL that offer the easiness of externally mounted standard elbow spokes and the widest possible camber of all spoke flanges.

* Shortest gear ratio 1:1
CyberRear freewheel mechanisms are suitable for road and cyclocross use (and not MTB) with a maximum shortest ratio of 1:1.
Shorter ratios may produce excessive torque and damage freewheel mechanism.
