38 TwentyFour Carbon Clincher Wheelset V2 by Profile Design
If you walked into any high-end bike shop in the '90s, you'd see the Profile Design logo prominently displayed as the premiere brand for aero bars and wind-cutting triathlon accessories. Since then, Profile has expanded its offerings with additional componentry, including wheels. With the 38/TwentyFour Carbon Clincher Wheelset, Profile Design combines its expertise in aerodynamics with a reputation for durability to deliver a solid all-rounder that can climb quickly, corner confidently, and carry speed with less effort. Profile's engineers camped out in the wind tunnel with Computation Fluid Dynamics specialists to analyze testing data and determine the best rim shape for low drag and solid crosswind handling. To replicate real-world situations, they even mapped out weather data from recent high-level cycling and triathlon events to recreate those wind conditions in the tunnel. The result of all this work is a wheel that isn't just fast in the virtual lab--it's fast out on the pavement in real-world wind conditions. The specs are in the name with these wheels. The 38/TwentyFours feature a 38-millimeter rim that provides just enough aerodynamics to slice through the wind while maintaining a relatively low profile in crosswinds, so you're not blown from side to side. Additionally, they feature slightly curved sides with a rounded spoke-facing edge that manages the lateral force of crosswinds for better stability than traditional airfoil rims. Profile uses its own high Tg point resin on the carbon braking surface for a claimed 30-percent increase in heat capacity, when compared to other high Tg resins used in the industry. This means, in theory, these wheels have better, more consistent braking across changing conditions and long descents than the competition. So put away the hourly temperature reports and radar forecasts and go out and ride with confidence that you'll be able to stop at a moment's notice in any weather without risking a catastrophic rim failure....

Maine ocean islands provide the only nesting sites for Atlantic puffins in the United States. Eastern Egg Rock in the midcoast region, Seal Island and Matinicus Rock at the mouth of Penobscot Bay, and Machias Seal Island and Petit Manan Island off the downeast coast provide habitat for more than 4,000 puffins each summer.
