Ridley Helium SL 10 Carbon Road Bike with Carbon Zipp 202 Wheelset


The Ridley Helium SL 10 is a superlight race bike with an amazing approximate frame weight of 750g. Made from oversized, extremely high modulus carbon the Helium frame has been engineered to be particularly light 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. Ridley’s lightest racer offers the best combination of stiffness, low weight and all-day comfort making it equally suited to the Brutal Belgian pave and Tour de France hors category climbs.


Helium Frame Features:

  • Extremely high modulus aerospace carbon used in combination with nano-resin to save weight without reducing stiffness
  • Oversized round shaped tubes offer the best stiffness to weight ratio
  • Carbon rear dropouts with a reinforced steel plate for increased durability
  • Specially designed oversized PF30 bottom bracket offering a 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
  • Curved fork blades specially designed to combine stiffness, low weight and comfort
  • Frame compatible with electronic and mechanical shifting

Mr TUCKER Easily the best bike I've owned. It's incredibly light and amazingly responsive. I set new records on just about every Strava segment on the first ride.
