Hyper3 freewheel kits are compatible with HyperBoost3 R - HyperSmart3 R.
Not compatible with the elder version 1 and 2 of HyperHubs.
Each kit includes freewheel body, its specific floating ring, 1set of stainless springs, 2 bearings, 5cc of Alugrease Super1.
36 points of engagement (p.o.e.) suitable also for E-Bike applications, less sensible to adjusting errors of Micro-Tuner, slightly easier maintenance.
48 points of engagement (p.o.e.) offer a faster response and a lower coasting friction than most conventional road hubs.
Shimano MTB 12s (Microspline 10T compatible) Kit includes also it's specific cog lock-ring.
Shimano MTB 12s (Microspline 9T compatible) accepts Shimano lock-ring.

Important tech notes:
Check well the conditions of hub-shell splines before ordering a new Freewheel Kit.
Follow instruction manual step by step, do not skip any!
Never mix parts between used and new Freewheels!

Tech Tips

Hyper "3 & 3+" hubs (This hub family includes " HyperBoost3-R " " HyperSmart3-R & R+ ")
Hyper hubs have been long-term tested in the wet environment of north Europe from the start.
For over a decade we have constantly developed and refined each single detail of our Hyper hubs.
Properly maintained hubsets reach a very remarkable lifespan, read below how to.

Start-up and Breaking-in
Remind to check the Micro-Tuner is properly tuned before the first ride. All hubs are pre-tuned at the factory assembly but consider that after the rim lacing and the wheel installation with cogs and disc on the bike chances are that the Micro-Tuner get unitentionally mis-placed.
To properly set upthe Micro-Tuner position just follow the Bearing-Preload instructions on the hub manual with the wheel on the bike.
As start please ride the hub for 4-8 hours at mild intensity (coasting reduces the break-in time) to allow the first breaking-in of the moving parts.
This will allow the correct "smoothing" of the moving surfaces just like on other hi-precision mechanisms ie thermic engines.

Never spray-wash hubs in general (any model of any brand).
Avoid high-pressure washing directly onto freewheel, even the best lip-seals aren't capable to resist to hi-frequency water spray.
When water-moisture get inside the hub mechanism it carries dirt particles too, these can quickly damage the internal hub parts.
The amount of wear depends on the quantity of dirt laying inside, the mileage, and how abrasive are the dirt fine particles.
These 3 factors combined can bring to a premature wear of bearings, hub-shell splines and freehub mechanism.

"Hyper" hubs bearings
All models of "Hyper" hub family feature unique external O-ring seals for an additional protection of the bearing seals and are standard equipped with Enduro 440 stainless bearings that do not suffer for oxidation-corrosion.
In clean conditions good bearings can last for 30-40.000 Km, however in the mtb riding environment water can get in bringing fine abrasive dirt particles with it.
For the reason described above the wear of metal races and balls directly depends to the type and amount of dirt that get inside the races.
All models can be ordered with optional super-high grade steel and non-corrodable Ceramic bearings for reduced friction and longer lifespan: HyperCeramic or Enduro XD-15.

"Hyper" hubs Servicing / Frequent Errors
We warmly recommend to learn the basics about our MTB engagement system from the start in order to ensure an extended durability of your hub.
Hyper freehub mechanism works in a far different way than other front-engagement hubs you may already know (ChrisKing / DT / others).
Never wrench on Hyper hubs by instinct or past experience but read manuals and strictly follow the instructions step by step (don't skip any step).

Understanding "Hyper" freehub principle is extremely important.
HyperRear freehub function is fully based on the velocity of "Floating-Ring" movement.
"Floating-Ring" movement should happen instantly ( one millisecond only) and this dictates the servicing rules you find on our manuals.
Once few engagement teeth got damaged by a slow / un-free movement of the Floating Ring the entire freewheel assembly must be replaced.

Avoid the following errors that will seriously damage the hub internal parts (immediately or in a very short time):
- Too much grease.
- Uncorrect positioning of grease. Never apply grease on hub-shell splines (oil them only).
- Wrong grease type (Lithium grease is one of the most dangerous).
- Micro Tuner way off its correct position (this increases also the clearance between the engagement teeth)

Regularly service your Hyper hub strictly following its instruction manual step by step (don't skip any step).
Again: never wrench or service Extralite hubs by instinct or only by past experience!

Old and new parts
As you see the first signs of wear we warmly recommend to install a new Floating Ring, it will help to prevent wear of hubshell splines.
Never install a worn-out Floating Ring in a still good hubshell, it will quickly damage and wear the hubshell splines!
All "3" hub models benefit of over 12 years of continuos developement and offer the longer lifespan of every part.

Hubshell Splines - Potential risk
When riding with dirt inside the freewheel mechanism the hard particles of sand will badly grind the hubshell splines.
As the "floating ring" doesn't move well and instantly a freewheel mis-engagement can permanently damages the freewheel parts.
In this case replacing "floating ring" and/or "Freewheel body" does not solve.
See this example of badly worn-out hubshell splines that need an expensive hub-shell replacement (or eventually sent back for re-sharpening).
