HyperSmart 3+ Hubset 213g

Super adaptive, yet incredibly light and precise.

HyperSmart3+ F offers the same axle stiffnes both if TA12 or QR15 featuring on both versions a Ø17mm axle and beef 6803-2RS bearings.

Equipped with 17-26mm corrosion resistant stainless bearings on an oversized axle that is multi-shaped and individually lapped to micro tolerances

Micro-tuner ensures a very precise bearing setting: minimum bearing friction with highest bearing durability and no play at the rim

Additional external Soft-Touch O-ring seals keep dus and moisture away from the 2RS bearing seals promoting bearing longevity

HyperSmart3+ R offers the max spoke camber for MTB lacing and self-adapts when equipped with road-gravel freewheels

Combine HyperSmart3+ R with Black-lock and get a tricky super-stiff assembly

The overall hub system is the world lightest and employs bigger bearings than most competitors
Freehub employs 2 corrosion resistant stainless bearings (6803-2rs), hubshell rotates on a"heavy duty"
(6903-2rs) corrosion resistant stainless main bearing that can handle 250kg and a low friction (6803-2rs) bearing on disc side

Available with MTB and Gravel-road freewheels

Third generation of Extralite's front engagement system increases the gap with the competition
20% lighter floating-ring enhances engagement quickness and also reduces noise and drag
Newly developed hubshell splines increase overall lifespan over 35% and simplifies maintenance
Specifically designed long-life polyurethane Lip seal protects the freewheel mechanism from the elements

Angled 3D Drilled spokes ensure a perfect head alignment

Configure

Race-proof hyper-engineered disc hubset, compatible with MTB, Gravel and Road cogs.
Ø 2.8mm spoke holes are 3D angled and rounded for perfect spoke-to-rim alignment & optimized spoke camber.
The 3D angled drilling with smooth rounded transitions allows to directly fit Berd and Carbon-metal spokes besides traditional butted steel spokes.
ABI Stainless cartridge bearings with high load capacity & low friction RS seals plus external O-ring seals.
Oversized 17mm axle with external micro- tuner.
Black anodized body with laser etched graphics.

Wheel building instructions for
HyperBoost3 F / Smart3 F - HyperBoost3 R / Smart3 R - HyperLefty3

Here you find all the necessary instructions to build up your dream wheels with pre-calculated spoke lengths.

Follow instructions step by step:

1) Measure your "Spoke-End Diameter"

2) Find your spoke length on table

3) See specific notes about spoke and rim types

4) Follow correct lacing pattern

Rim offset:
2-3mm of rim offset influences the spoke length for an average 0.3mm only.
You may neglect it or eventually just use that tiny amount for rounding lengths to the available spoke size.

Maximum spoke tension: Refer to specific manuals

Spoke lacing and tensioning require skills and experience, refer to an expert professional wheel builder for these operations.

1) "Spoke-End-Diameter"

Rim manufacturers offer ERD figures however we warmly recommend to precisely measure the rim+nipple combination.

Basically a correct spoke calculation requires exact "Spoke-End-Diameter" and rim drilling.

Spoke-end diameter depends on your rim internal diameter and nipple type too.

Table A

We list "spoke-end diameters" every 5mm step. If your "spoke-end diameter" measure is in between 2 steps adjust your spoke length consequently.

3) Important Notes

Rims: We consider rims with 2-4mm of offset.
In case of symmetric rims you may add 1mm to front-right and rear-left sides.

Steel Spokes: Flanges accept standard spoke heads however we recommend to use only high quality butted spokes.
Butted spokes are lighter and allow a better spoke aligningment that translates in a reduced stress of the parts and an overall stiffer lacing.

Berd spokes: Flanges are designed to fit Berd spokes.
All edges are well rounded thereafter "Tangential Straightpull Inserts" are not necessary.
Consequently adjust Table A lenghts as follows:
- subtract 2mm from Table values if "Without Tangential Straightpull Inserts"
- keep values on Table if "With Tangential Straightpull Inserts"

Berd Tangential Straightpull Insert

WARNING: never modify even slightly the flanges of Extralite hubs not their surface finish.

4) Lacing:
correct lacing patterns with straight-pull spokes must be tangential, exactly as shown below
(and not as the traditional 2 or 3 crossings used for elbow spokes)

Warning: spoke lacing and tensioning require skills and experience, refer to an expert professional wheel builder for these operations.

How to measure "Spoke-End-Diameter"

Spoke-end diameter depends on your rim and nipple type and length.

Below you see how to measure SED for both nipple types:
External nipple configuration
Internal nipple configuration

Take measures very precisely because a well correct nipple/spoke assembly accepts a spoke-length tolerance of +/-1mm only.
(All measures are expressed in mm)

External nipple configuration

1) Insert two J-spokes (random size) with the nipples (of your final build) into 2 opposite rim holes.

This simple trick helps to keep spokes aligned and slightly tensioned.

2) Precisely measure distance between nipples.

Be careful to take measure between the 2 nipple-ends.

3) Add 2x by the nipple height (of your final build) to the measure above.
This gives "Spoke-End-Diameter".
Note: with slotted nipples measure height inside the cut.

cutted nipple

Internal nipple configuration

You can get the necessary data following the procedure below:
1) Precisely measure outer rim diameter (A).

2) Insert a nipple of your final build into a hole (use a spoke to hold nipple in position).
3) Precisely measure distance between nipple-top and outer rim diameter (B).
