Developed to meet the demands of cyclists like Movistar's Quintana, the Bora Ultra 35 Clincher Wheelset represents the best of the best for mixed terrain racing. Its profile strikes the sweet spot between low weight for climbing and deep aerodynamics, and the addition of Campagnolo's 3Diamant braking texture and peerless CULT ceramic bearings mean it stops, starts, and spins better than almost any other wheelset in the peloton. Not only does the Bora Ultra 35 rim cut through the wind like a medical-grade scalpel, it also features an updated rim width. For 2015, the Bora's width is increased to 24. 2 millimeters, which expands the tire's volume and straightens the sidewalls. This makes for more secure grip in corners and lower rolling resistance while letting you run a lower PSI for a cushier ride. The width also nets better lateral stiffness, more structural integrity, and a" in a counter-intuitive twist a" actually improves aerodynamics. The CULT cup and cone bearings are behind Campagnolo hubs' legendary rolling performance. CULT marries the smoothest ceramic bearings with thermochemically treated Cronitect races for a claimed 3. 5 more watts per pedal stroke over non-CULT bearings. The interface between the ceramic balls and Cronitect races is so smooth that they virtually don't wear out and only require a thin film of oil instead of grease. All told, Campagnolo touts these as the lowest friction bearings in the world. While we normally approach anything that smacks of marketing hyperbole with healthy skepticism, taking the Boras for a spin lends credence to Campy's claim. A good wheel can't just go well; it also has to stop well, and the new 3Diamant braking surface addresses some of the key braking issues we've had with carbon rims in the past. Campagnolo literally uses diamonds to hone the brake track to near perfection, removing imperfections and resin so that the pads connect straight to a strip of slightly textured carbon. This reduces the time it t...

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.
