Ultralight Bike Hubs for Road, Gravel and MTB

Precision Hub Engineering for Maximum Performance

For more than 25 years, Extralite has developed some of the lightest and most advanced cycling components in the world.
Among the brand’s most iconic products, Extralite hubs represent the perfect balance between ultra-low weight, mechanical efficiency, durability, and precision engineering.
Designed and manufactured in Italy, Extralite hub systems are developed for riders who demand uncompromising performance across Road, Gravel, MTB and Offroad disciplines.

Every gram is optimized.
Every detail is engineered.
Every watt is preserved.

 

Why Lightweight Bike Hubs Matter

Hubs are one of the most critical rotating components on a bicycle.
Reducing hub weight improves:

  • Acceleration responsiveness
  • Climbing efficiency
  • Wheel reactivity
  • Overall ride feel
  • Rider energy count

At the same time hub engineering directly enhances:

  • Noise reduction
  • Friction reduction under load
  • Power transfer efficiency
  • Bearing performance and durability
  • Long-term maintenance requirements

Extralite combines discipline-specific engineering solutions with advanced machining technologies to create hubs truly optimized for real-world riding conditions.

 

Two Dedicated Hub Platforms: Cyber & Hyper

Rather than creating a single compromise solution, Extralite developed two completely dedicated hub families:

  • Cyber hubs sepecifically engineered for Road riding
  • Hyper hubs sepecifically designed for MTB, Gravel and Offroad use

Each lineup is engineered around the specific performance demands of its discipline: torque loads, riding environment, noise levels and mileage.

 

Cyber Hubs: Ultra-Light Road Performance

The entire Cyber hub lineup is specifically designed for Road Racing and Road Training; both require:

  • Low rolling resistance
  • Minimal coasting friction
  • Silent operation
  • Highest possible spoke camber
  • High mileage and reliability
  • Reduced maintenance intervals

All members of the Cyber hub family share Extralite's advanced pawls-and-ratchet freehub system.
Its unique and tricky engineering promotes several advantages:

  • Exceptional mileage
  • Smooth engagement
  • Less coasting fricton
  • Quietest possible coasting
  • No rustable nor corrodable parts
  • Long-term efficiency

Since road cycling typically involves lower torque loads and cleaner riding conditions than MTB, Cyber hubs are optimized to maximize the mechanical efficiency and to achieve the widest possible spoke camber.
The result is a lightweight hub platform capable of delivering elite-level road performance with outstanding reliability without limitationsof rider weight thanks to the oversized and carefully dimensioned hub structure.

 

Hyper Hubs: Built for MTB & Offroad Riding

The Hyper hub lineup is specifically engineered for MTB, Cross-Country, Marathon, Gravel and Offroad riding in general.
Mountain biking generates significantly higher loads due to:

  • Short gear ratios
  • Explosive accelerations
  • Technical climbs
  • Harsh terrain impacts

To handle these conditions all Hyper hubs feature oversized structure and Extralite's proprietary front-engagement system.
Our freewheel mechanism is designed to withstand offroad high torque stresses while being entirely made of hi-strenght alloy.
Our advanced system offers several advantages:

  • High load capability
  • Extremely fast engagement
  • Extremely lightweight
  • No rustable nor corrodable parts
  • Durable polyurethane lip-seal protection

Because of the demanding offroad environment, Hyper hubs are equipped as standard with:

  • Very high structural strenght, bigger axles, bodies, flanges and bearings
  • Outstanding protection against the elements
  • Additional external O-ring seal system (lubed) 
  • Freehub protected by Polyurethane lip-seal
  • Non-corrodable bearings: HyperCeramic, Enduro XD-15 or ABI 440C

Extralite's engineering approach ensures maximum performances even under extreme offroad racing conditions at feather weight.

Micro-Tuner: Ultra-Precise Bearing Adjustment

All Extralite hubs are equipped with the proprietary Micro-Tuner system.
The ultra-accurate bearing preload adjustment device offers:

  • Precise calibration of bearing preload
  • Reducuction of rolling resistance
  • Longer bearing lifespan
  • Zero play at the rim

The system is designed to reduce rolling friction for race-level performance while enhancing bearing durability with a super-easy access.

 

Advanced Bearing Technologies

Extralite hubs are available with premium bearings:

  • HyperCeramic  (by Extralite)
  • Enduro XD-15  (by ABI industries)

These high-end solutions provide:

  • Exceptional smoothness
  • Reduced friction under load
  • Fully resistant to corrosion
  • Long-term durability 

Every bearing is individually selected and matched to the hub-unit to achieve the most correct fitting pressure and efficiency.

 

Engineered for Riders Who Push Limits

Whether you ride:

  • Lightweight Road bikes
  • Competitive Gravel bikes
  • Cross-country MTB
  • Marathon setups
  • Custom performance builds

Extralite hubs are engineered for who care about every bit of efficiency:

  • Unmatched lightness
  • Immediate acceleration
  • Precision power transfer
  • Maximum spoke camber
  • Long-term reliability
  • Elite-level riding performance

More Than Lightweight

Extralite does not simply reduce weight.
Every hub is developed through a performance engineering philosophy focused on:

  • Structural efficiency
  • Mechanical precision
  • Rotational optimization
  • Reliability in real riding conditions

This is not just lightweight engineering.
This means speed, precision and efficiency without compromise.
