Impossibly steep switchbacks and long alpine roads are made to be ridden, and the Helium X 40 was made to ride them. Combining wind-cheating aerodynamics with a barely-UCI-legal frame weight (about 900 grams in a medium), it's a race-ready weapon with an advantage in the mountains. The massive pressfit BB and oversized tapered headtube provide immediate response when you break away from the pack. Once you've moved away, the DT Swiss R460 rims laced onto Shimano hubs provide stiffness and fast-rolling bearings to transfer every watt of effort to the road. A dropped chain or missed shift can be a race decider, so Ridley opted for one of the most reliable setups around: Shimano Ultegra. When going for a race-winning move on technical descents, the powerful Shimano Ultegra brakes allow you to brake later before leaning hard into corners. Finally, a host of proven 4ZA aluminum and carbon components tie this race-ready steed together.
