Features
HyperHubs offers unique features like low friction external OR
and lip seals, front engagement freewheel system, multishaped
oversized axle, top quality sealed stainless ball bearings, Micro-
Tuner bearing preload system, “hart coat” anodized cassette
body and axle ends.
Bearings: 2x 6903 2RS (hub body) and 2X 6803 2RS (freewheel).
Use it proper care and its absolute performance will last for
years. This manual provides the informations needed for the set
up and the basic cleaning-lubing-maintenance.
Destination
Cross country, Enduro.
Guideline
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 next page.
Never use high-pressure spray washing directly on hubs. Clean hubs externally with warm water and soap.
WARNINg
Avoid the following errors that will seriously damage the hub internal parts (immediately or in a very short time):
-
Too much greasing.
-
Uncorrect positioning of grease.
-
Wrong grease type (Lithium grease is the most dangerous).
-
Micro Tuner way off its correct range (this increases also the clearance between engagement teeth)
-
Never couple new engagement parts in contact with worn-out ones.
Once engagement teeth got damaged by a slow / un-free movement of the Floating Ring there is no other way than replace the entire
Freewheel assembly.
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 / axle.
2) If you feel play at the rim turn in Micro-Tuner (clockwise). Use a 21
mm 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 bring to serious damages:
- Too tight --> bearings damage and premature wear
- Too loose -->permanent freewheel damage

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.

Disassembly for cleaning.
Maintenance (level 1).
1) Hold Left Axle End with a
17mm closed wrench for 142mm
(
5mm hex wrench for 135mm Quick Release
)
.
2) Unscrew and remove Right Axle End.
3) Pull Freewheel Body and remove it.
4) Extract Axle by pushing it from right side.
5) Clean all parts (do not use aggressive solvents).
Lubrification and reassembly
1) Slightly grease bearing contact surfaces on Axle.
2) Insert Axle from left side gently pushing it with a plastic mallet.
3) Temporary unscrew out Micro Tuner for 1to2 turns.
Avoid screwing it to prevent damages.
4) Grease freewheel area with 2cc. of very soft density grease as original Alugrease Super1. Never use Lithium, additivated
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) Grease 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 next page.

Sealing
HyperRear hub features low friction Lip Seal and external OR seals. However, since it is impossible to completely seal a hub and still have it spin freely, with use water/moisture can get in.
Lock Ring maximum torque:
Shimano 10/M11s --> 25Nm
Shima 12s compatible --> 12 Nm
Use only Extralite S12 Lock-Ring
Never use original Shimano Lock-Ring
Micro Tuner:
21mm wrench.
Secure rotor bolts with mild
threadlock (Loctite 243)
6Nm
Bearing preload set-up:
Optimal bearing preload is important for a long bearing life. Incorrect bearing preload can damage bearings and freewheel parts
additionally decreases hub performance.
Micro Tuner comes pre-adjusted from the factory. Do not modify its position if not necessary.
Warning
-
Riding with a too-tight Micro-Tuner reduce bearing life and performance.
-
Riding with a loosen Micro-Tuner may causes an uncomplete freewheel engagement and damages mechanism permanently.
- Never insert a worn-out float-ring into a row of new hub-
splines on Hyper1 & Hyper2. (Hyper 2+ series employs all 24
splines)
Once engagement teeth got damaged by a slow / un-free
movement of the Floating Ring there is no other way than
replace the entire Freewheel assembly.
