HELIUM SL 1305A

HELIUM SL 1305A

Superlight race bike, approximate weight: 750g. The oversized tube shape is engineered with the use of extremely high modulus carbon. This results in a very light frame, without compromising stiffness. The dual purpose internal cable routing uses the same holes for mechanical and electronic shifting, resulting in a very clean design without excess holes. Flex seat stays increase vertical compliance for additional comfort, without reducing lateral stiffness.

• Use of extremely high modulus aerospace carbon in combination with nano resin to save weight without reducing stiffness.
• Tubes, designed following Ridley’s “form follows function” philosophy.
• Carbon rear dropouts with a reinforced steel plate for increased durability.
• Specially designed oversized press fit BB30 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.
• Compatible with electronic and mechanical shifting
• Curved fork blades, specially designed to combine good stiffness, low weight and the right amount of comfort.

Frame: 60, 40, 30 ton high modulus carbonc
