Craftworx Ultima Carbon Sprint SL 'HD' Road Wheel Set

Our Flagship Lightweight Carbon Wheel Set - 1439 gram climbing weapons for heavier riders

The benchmark for performance in lightweight carbon road wheels. SL stands for Super Light. We've shred every gram of excess weight without compromising on strength and durability. This HD version adds more stiffness to the wheel making it more suitable for heavier riders up to 110kgs

The 28mm deep front wheel reduces weight and improves handling. The 38mm rear wheel improves aerodynamics and power transfer for faster riding.

Lighter weight wheels that will make a meal out of the climbs. They are right at home on bunch rides, road races, triathlons and anything else.

Climb with ease and descend with confidence. Our specially developed brake pads give you loads of stopping power in all conditions.

OUR ABSOLUTE LIGHTEST CARBON ROAD WHEELS -These wheels take our amazing Ultima C38 set to the next level.

  • The HD - Heavy Duty version of the Ultima Sprint SL is still light but has been strengthened with additional spokes and a beefed up hub. this increases the stiffness for riders up to 110kg.
  • Lower profile C28 front rim to reduce weight, improve handling and reduce effects of cross winds on the wheel. This results in quicker acceleration, easier directional change and a more stable ride.
  • Upgraded to our Craftworx Ultima SL hubs. At only 247 grams, these are one of the lightest hubs on the market. But unlike some 'lightweight' hubs that cut corners and leave things out, we have achived crazy low weights through better engineering, design and superior materials.
  • Upgraded to bladed spokes. Bladed spokes are butted (thinned out to reduce weight) and the flattened reducing their footprint in the air, therefore creating less drag. This also makes the spoke lighter and stronger - Win + Win!
  • Upgraded quick release skewers to our Titanium version for extra weight saving (only 16 grams, but every little bit counts!!)
    Will I notice a difference you ask?? You betcha! As good as the Ultima C38's are, these are next level again!

    The Result is a lighter and more responsive wheel set for riders who want greater performance.
