Technology:

2-Way Fit™:
- Tubeless Technology Was First Used By The Auto Industry , Then By Motorcycles And Now Has Reached The Cycling Industry. After Its Debut With Mountain Bikes The Moment Has Come To “Put It On The Road”, And That’S What We Propose To Do.
- We Have Developed Our 2-Way Fit™ Technology To Ensure The Perfect Compatibility Of Our Tubeless Rims With Normal Clincher Types And Tubes. 2-Way Fit™Road Bike Wheels Are Perfectly Multipurpose For Tackling Every Situation. Thanks To A Special Impression In The Valve Area, The Tubes Are Fitted With The Maximum Precision While Keeping The Tube Perfectly Stable Inside The Tyre.
- Housing The Valve For Tubeless Tyres Is Also Risk-Free, With The Unquestionable Advantage That There Are Never Any Air Infiltrations Caused By Non-Ideal Positioning When Fitting.

Compatibility:
- It Shall Be The End User’S Sole And Full Responsibility To Choose - On A Case By Case Basis – An Adequate And Correct Rim-Tire-Pressure Combination, As Well As To Conduct All Verifications Neces-Sary To Ascertain The Correctness And Safety Of Such Combination.
- Without Prejudice To The Above, And In Order To Ensure Optimum Rolling Resistance, Grip And, Most Importantly, Safety, We Recommend That The End User, In Making His Choice, Also Takes Into Consideration The Recommended Combinations Of Hooked Rim Width, Tire Width And Tire Pressure Indicated In The Chart Set Forth Below.
- Due To Safety Reasons, Follow The Information Of The Tire Manufacturer Regarding Minimum And Maximum Rim Width To Be Used But Always Ensure That The Combination Is Listed As Possible In This Table.

Usb™ - Ceramic Ultra Smooth Bearings™:
- Fulcrum® Has A Long-Standing Reputation For The Extremely High Performance Of Its Hubs In Terms Of Smoothness And Reliability.
- In Fact, All The Projects Are Entirely Developed In Our R&D Department And We Have Put Obsessive Care Into Taking Care Of Every Detail.
- The Hubs With Usb™ Ceramic Bearings (Ultra Smooth Bearings) Further Enhance The Triathlon And Road Bike Wheels’ Smoothness And Reduce Weight And The Need For Maintenance.

50% Smoother:
- Comparative Tests Have Shown That Usb™ Bearings Are 50% Smoother Than Standard Bearings.
- Now Improving Your Performance During The Race Or Simply Going For A Ride With Your Friends Will Be Easier.

2:1 Two-To-One™:
- When You Push On The Pedals, The Rotational Force On The Sprocket Induces A Slackening Of The Freewheel Spokes With A Consequent Loss Of Rim Tension.
- This Results In Undesirable Flex Of The Whole Wheel And An Unavoidable Loss Of Energy. Fulcrum® Has Solved This Classic Cycling Problem With Its 2:1 Two-To-One™ Spoke Ratio Patent, By Doubling The Spokes In The Critical Zones.

Drsc™ - Directionated Rim-Spoke Coupling:
- Exclusive Rim/Spoke Coupling System. It Allows The Rim, Spokes, Nipples And Hub To Align Properly With The Same Tensioning Value In All Areas.

Momag™:
- A Magnet And Lots Of Ingenuity. This Was What Led To The Patent For The Well-Tested “Mounting Magnet” System, Or Momag™.

F.I.C. Fulcrum Identification Card - 100% Handmade Quality:
- Right From Its Inception Fulcrum® Has Been Marked By Feature That Continues To This Day: That Is To Design, Prototype And Industrialise All The Wheels Characterised By The Red “F”. Indeed These Take Shape Inside Of The R&D, The Leading-Edge Department That Represents The Beating Heart Of The Italian Company. Every Single Component Of The Wheel, The Materials Chosen And The Technologies Applied Are The Tangible Result Of The Effort That Fulcrum® Makes Every Day To Give You Maximum Performance And Reliability.

Afs Axle System™:
- The Axial Fixing System™ Is The Solution Developed By Fulcrum® To Fix The Disc Brake To The Hub. The Constraint Granted By The Butt Area Of The Release Mechanism, Greater Than In Familiar Standard Ones, Makes It Possible To Obtain Greater Structural Rigidity And Therefore More Precise And Powerful Braking.

Rim Full Carbon Technology:
- Full Carbon Fulcrum® Rims Are Built Using Combinations, Developed In The Laboratory, Of Different Types Of Fibre, Including Ud And The Famous 90-Degree 3k Of Models At The Top Of Our Range. To Build Them We Developed A Special Htg (High Transition Grade) Resin, Whose Glass Transition Point Is At A Higher Temperature Than Any Other Fibre Used In The Bicycle Industry. This Gives Incomparable Performance When Braking.

Undrilled Rim Bed:
- The Advantages Are Immediately Clear: Less Weight, Longer Lasting Rims, Greater Resistance To Fatigue, The Possibility Of Giving The Spokes More Tension And More Stiffness Which, In Terms Of Performance, Means Improved Responsiveness And Acceleration.

Cup & Cone:
- The Cup-And-Cone Bearing Differs From The Classic Cartridge Bearing Because It Works In Perfect Alignment With The Forces Involved, Weight And Thrust From The Frame, As The Bearings Run In A Race Positioned Directly Opposing These Forces.

Asymmetric Rim:
- The Asymmetry Is Designed To Improve Rim Tension, Balancing The Forces From Brakes And Sprocket Cassette.
