Road frameset RIDLEY HELIUM DISC - color HED-01As (Black-White-Merlot Pearl)

The Helium Disc performance road bike contains all the unprecedented cycling qualities and superb technology that go into the top-of-the-line Helium SLX Disc, but with a much lower price tag. The Helium Disc road bike incorporates the unique oval tube shape which perfectly balances stiffness, weight and comfort. In addition, all cables are fully integrated in the Helium thanks to the F-Steerer technology. This gives it a clean look that's maintenance-free. What you'll feel is how light, reactive, stiff and comfortable it is to ride - from first to last pedal stroke. 

• use of high modulus carbon to save weight without reducing stiffness
• oversized round tube shape offer the best stiffness to weight ratio
• use of 12 mm thru-axle increased the frame’s stiffness
• specially designed oversized PF30 bottom bracket offers a very high level of stiffness for maximal power transfer
• tapered 1 1/8 - 1 1/4 head tube with angular contact bearings
• flex seat stays provide comfort without sacrificing stiffness
• straight blade fork adds to that sublime handling taking hairpin bends
• aerodynamically optimized by using F-Steerer technology - every cable can be integrated to create a clean cockpit
