78 TwentyFour Carbon Clincher Wheel V2 by Profile Design
Profile Design is no stranger in producing components that help you go faster and has been an industry leader in aerobar design for decades. It's recently taken its aero expertise and development and instilled it into wheel designs and the particular wheel we have here is the 78 TwentyFour Carbon Clincher Wheel V2. Perhaps not the first name that comes to mind when thinking about carbon wheels, however, the materials and design philosophy are solid and this wheel comes in at a much lower price point than some of its competitors. When creating the rim shape for the 78/TwentyFour, Profile used Computational Fluid Dynamics and logged many hours in the wind tunnel to determine the best profile that reduced drag and remained steady in crosswinds. Part of the criteria involved mapping out weather patterns at high-profile triathlon event locations to recreate real-world wind yaw angle conditions to test the wheel's behavior and gather this information in the wind tunnel. This development is unique in that it tests likely real-world scenarios in a lab environment so when out on the open road the wheel will perform as designed with that said goal of less drag and more stability. As you probably already guessed, the rim's dimensions are in the name, 78mm deep with an external width of 24. 5mm. That external width plays nice with the current trend of wider 25-28mm road tires and affords a lower pressure contributing to a plusher ride with lower rolling resistance. The rim's shape bulges slightly, with a rounded spoke-facing edge to help better manage crosswinds for more stability than traditional airfoil rims. Profile uses its own high Tg point resin at the carbon braking surface for a claimed 30% increase in heat capacity compared to other high Tg resins commonly used in the industry. This correlates to more powerful and better modulating braking, even during inclement weather conditions and long descents than other carbon braking surfaces. The wheels also come with sp...

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.
