It's no secret that aero bikes can help you go faster; after all, they've been around for years. The issue has traditionally been a sacrifice in lateral stiffness or a harsh ride associated with building a frame with aero tubes. That is until technology finally caught up with the recent aero designs over the past several seasons, allowing you to have your cake and eat it too. Science tells us that aero drag accounts for as much as 90 percent of the overall resistance and less drag simply equals more speed. So if you can have an aero advantage, enjoy a smooth ride, and get the proper stiffness needed for rock-solid sprinting and sure handling why wouldn't you choose a frame like this' Good question. The S3 Road Frameset is such an option and the one we would suggest if you value the simplicity and lightweight build of a rim brake bike.Cervelo honed the S3's aerodynamics after spending countless hours in the wind tunnel testing and refining designs. This particular disc model features full internal cable routing thanks to a new bar and stem that hides the brake and shift housing from the wind for improved aerodynamics. Additionally, the new frame profiles work together to reduce drag so you simply go faster. Cervelo calls this True Aero which combines these specific tube shapes, sizes, and design features to improve aerodynamic flow across the bike.The most aero bike available is meaningless if it's a wet noodle though, so thankfully Cervelo worked hard to increase the stiffness at the bottom bracket shell ensuring efficient power transfer and that every watt goes straight to the rear wheel. Just like every other Cervelo, the S3 uses its BBright shell which takes advantage of oversized frame tubes that are stiffer and lighter. With the BBright system, larger sized tubes are used at the seat tube, down tube, and non-driveside chainstay. The benefit is an increase in stiffness and pedaling efficiency while achieving a lighter weight frame that's compatible with all...

Rising above a scene rich with extraordinary wildlife, pristine lakes, and alpine terrain, the Teton Range stands monument to the people who fought to protect it. These are mountains of the imagination. Mountains that led to the creation of Grand Teton National Park where you can explore over two hundred miles of trails, float the Snake River or enjoy the serenity of this remarkable place.
The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
