Tour tech: Road stage bikes go aero

The bulge at the top of the seat stays is intended to help direct airflow around the brake caliper.

  • Oval Concepts' R910 Aergo bar doesn't give much for the wind to look at.
  • Even the cables are routed internally to maintain the slippery shape.
  • The hourglass-shaped head tube is designed to minimize frontal area.
  • Now even climbing-specific wheels get some aero treatment as well such as the dimpled surface on these Zipp 202 rims.
  • Garmin-Chipotle's Julian Dean goes with an aero handlebar
  • The deep-profile integrated seatpost probably doesn't provide the smoothest ride but McEwen likely isn't going to care much about that
  • Ridley integrates Oval Concepts' JetStream technology into the seat stays…
  • The internal routing and complex frame shaping also means that Felt's designers had to get somewhat creative in regards to cable routing both below…
  • …and above the giant bottom bracket shell.
  • Whoops! This latest issue Shimano Dura-Ace lever is already missing its cover plate.
  • Garmin-Chipotle has a new aero frame from team sponsor Felt called the AR.
  • Derailleur housings are fed into the top tube right behind the stem where the air is already 'dirty'.
  • The bulge at the top of the seat stays is intended to help direct airflow around the brake caliper.
  • The seat tube employs shaping that is normally reserved only for races against the clock.
  • We're not sure how much of a difference this stem faceplate can possibly make but it probably doesn't hurt any.
  • Naturally, the seatpost is aero-shaped, too.
