Cervelo has been building aero road bikes for longer than most, knowing that adding aerodynamic elements to its road frames and reducing drag was an important ingredient in going fast, as aerodynamic drag accounts for as much as 90 percent of the overall resistance you encounter or a ride. We have fond memories of its alloy Soloist winning some of the sport's most prestigious races in the early 2000s and those aero traditions live on today. So if you are looking for an edge in fast road races, crits, or want a do-it-all machine for omniums, its S3 Disc Ultegra R8020 Complete Bike fits the bill nicely. In addition to more speed, it doesn't neglect a smooth ride, proper stiffness needed for efficiency and handling, refined geometry for sure handling, and good looks. 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 major bottom bracket standards. Stiffness doesn't just end there and C...

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.
