From its Shimano drivetrain to its bombproof Fulcrum wheels, the Ridley Helium RS 105 Complete Road Bike is built for the aspiring racer whose ambitions aren't captured in the marketing copy of the latest aerodynamic wonder toy. The Helium isn't made for the wind-tunnel life; instead, it's built for an efficient ride on climbs and sprints that won't shake you to pieces on rough roads at racing speed or while taking your paces through long winter base miles.
The Helium's namesake element happens to be one of the lightest on the periodic table, and the design of the frame reflects this, with a size medium weighing a claimed 880 grams. Ridley hits this low weight by blending two moduli of unidirectional carbon, 30T and 24T, in a strategic layup designed to keep weight down without sacrificing durability or stiffness. The tapered head tube contributes to this stiffness while you're hammering or climbing—the Helium's favorite pursuit—while also netting precise steering and laser-guided tracking through corners and swooping descents.
The Helium's thin, slightly flattened seatstays and standard 27.2mm seatpost prove that these designs are just as valuable to a comfortable ride today as they were when the need to sell new model years pushed other manufacturers to "innovate" with bizarre, unforgiving shapes. The rear triangle devours road noise and bumps like Helium's halogen cousins gobble up other molecules' electrons.
We'd like to say that the surprisingly precise action of Shimano's 11-speed 105 drivetrain takes us back to the days when we first tried Dura-Ace. But we can't. With all the technology that's trickled-down the Ultegra pipeline from the Dura-Ace source, the new 105 is every bit as sharp as the models ridden in the peloton as recently as a few years ago. As your abilities begin to eclipse your current ambitions, 105 will continue to grow with you.
