The Helium X frameset shares the same geometry and technology as our SLX model, as well as all the same benefits. The only difference between the two frames is that the X is slightly heavier due to an adjustment in carbon layup grades and ratios. It's a mixture of 30/24-ton high-modulus carbon fiber. This slight weight difference is offset by its lower price point.

• The Helium X utilizes the same technology as the WorldTour proven Helium SLX, but with a slightly different carbon layup
  

• With a weight of less than 900 grams, this frame is a perfect foundation for a true all-around, light, and stiff race bike
  

• The ultra-thin seat stays are engineered to offer comfort-enhancing vertical compliance and lateral stiffness
  

• Features a straight blade fork for improved handling and better aero performance compared to previous models, blades optimized to funnel air through the fork and decrease aerodynamic drag
  

• Shimano Ultegra drivetrain with Vittoria Zaffiro Pro tires and Rotor 3D30 Crank
