We always have fond memories of Zipp's 303 Firecrest Carbon Road Wheel, after all, it was the first carbon wheel to conquer Roubaix. With every new addition, the wheel gets a little more refined and as that old adage goes, "it never gets easier, you just go faster" these wheels might not make the riding any easier but you definitely reap the benefits of going faster and further with less effort with these hoops mounted up. Tubulars still rule the roost when it comes to discerning pros as the feel, weight savings, and safety during a flat still isn't matched with the current crop of clinchers and tubeless tires. The dimpling of Advanced Boundary Layer Control (ABLC) that Zipp relies on for aero supremacy returns on these wheels and are further refined through wind tunnel and real-world research and development. Along with the rims' signature bulge, ABLC also helps improve stability at common cycling yaw angles by directing side forces more toward the steering axis. We definitely appreciate ABLC -- if for no other reason than that it's become a staple in the peloton, winning races under names ranging from Cancellara to Armistead -- but we can't forget other high tech features like its Visco-Elastic Constrained Layer Control (VCLC) and Carbon Bridge. VCLC is similar to a construction model that we're seeing more and more in high-end frame manufacturing, especially among the venerable Italian names. It involves, to deconstruct Zipp's initialism, constraining a visco-elastic layer between the wheels' carbon fiber layers in order to increase the structure's ability to absorb and control road noise. As mentioned above, we're used to seeing this in racing frames, but Zipp may be the only manufacturer to bring it to wheels. The Carbon Bridge design incorporates Kevlar threads in the carbon layup to take advantage of Kevlar's 350% greater resistance to impact. The benefits throughout the wheel are obvious, but higher durability is especially welcome at the tire mounting s...

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.
