Destination
Road use, 130mm frames.
Guideline
Install Cog Lock Ring at a maximum torque of 25-30Nm.
Never use high-pressure spray washing directly onto the hub. Clean hubs externally with warm water and soap.
Periodically clean hub internals (every 6-12 months in normal and dry conditions, every 3 months in wet conditions and
always before leaving the wheel un-used for more than 1 month) see Level1 instructions.
Warning:
Water and moisture stagnant inside hub can permanently damage bearings.
Warning:
Use only very soft density pure grease as original Alugrease Super1, medium or hard density grease may
cause un-complete pawl engagement and this will seriously damage freewheel mechanism. Most greases contain
chemical additives that may damage OR Seals and, most of all, can break the freewheel OR spring.
Warning:
CyberRear mechanisms are suitable for road and cyclocross use (and not MTB),
shortest gear ratio 1.00
.
Shorter ratios may result in high torque and damage freewheel mechanism.

Lubrification and reassembly
1) Slightly grease bearing contact surfaces on Axle.
2) Insert Axle from right side gently pushing it with a plastic mallet.
3) Temporary screw in Micro Tuner for 2to3 turns only.
Avoid full turning to prevent damages.
4) Grease freewheel area with 2cc. of very soft density grease as original Alugrease Super1. Never use Lithium, additivated
grease nor thick grease
5) Oil OR-Seal with thin oil. Oils that are thicker than W40 engine oil may increase freewheel resistance.
6) Inserting Freewheel body: check the OR seal, OR Spring and Pawls are correctly positioned, carefully press pawls one by
one and partially insert freewheel. Check that pawls engage ratchet wheel properly then insert completely.
Do not pinch
seal OR
7) Grese threads and tighten Right Axle End at 7-8 Nm.
8) Gently push Axle from right side using a plastic mallet.
9) Gently fully screw in Micro Tuner and unscrew it for 1/4 to 1/2 of turn to release excessive preload on bearing balls.
10) Set-up bearing preload with preload tuning, see below.
Disassembly for cleaning.
Maintenance (level 1).
1) Extract Left Axle End by pulling it by hands.
2) Insert a 5mm hex wrench into Right Axle End.
3) Fully unscrew and extract Micro Tuner (use a 20mm wrench).
4) Insert a 5mm second hex wrench into left Axle side and unscrew Right Axle End.
5) Pull Freewheel Body and remove it.
6) Extract Axle by pulling it from right side.
7) Clean all parts.

Bearing preload set-up:
Optimal bearing preload is important for a long bearing
life.
Micro Tuner comes pre-adjusted from the factory. Do not
modify its position if not necessary.
Checking
Before modifying bearing preload carefully check the
complete wheel as follows:
1) Install wheel into dropouts and normally lock skewer.
2) Check there is no play at rim diameter.
3) Leave wheel free to completely stop spinning and
carefully control latest instants of movement. Stopping
should be very smooth.
Preload Tuning
If necessary fine tune as follows.
1) Install wheel into dropouts and normally lock skewer.
2) If you feel play at the rim turn in Micro Tuner (clockwise). Use
a 20mm wrench, very delicate torque and manners.
3) Unscrew Micro Tuner for ca 1/4 of turn to release excessive
preload on bearing balls and achieve max rolling
smoothness.
4) Repeat Preload Checking and eventually slightly correct it.
5) The optimal bearing preload cancels play at the rim
without affecting rolling smoothness.
Warning
Incorrect bearing preload can damage bearings
and freewheel parts additionally decreases hub performance.
