WARNING:
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.

* Minimum/shortest ratio
CyberRear freewheel mechanisms are suitable for road and cyclocross use (and not MTB), minimum 1.00 gear ratio.
Shorter ratios may result in high torque and damage freewheel mechanism.
