For cyclists not competing in the upper rungs of professional cycling, helmets have been sort of an afterthought in terms of providing free speed. However, things are rapidly shifting in the design of modern road helmets. Many are now balancing the needs of ventilation, protection, and streamlined aerodynamics in an attractive package for those cyclists competing in everything from their local crit series to endurance events where reducing drag is essential across long distances. In these instances, newly developed helmets like the POC Ventral Spin Raceday Helmet provide a leg up on the competition by saving precious watts and can be the difference between standing atop the podium and watching from a distance as the winners celebrate. This particular version of the POC Ventral Spin Raceday boasts race-specific colorways that are a bit more subdued than usual, but otherwise it remains exactly the same as the standard Ventral Spin Helmet. POC's Ventral Spin Helmet is touted as the most aerodynamic, well-ventilated, and safest road helmet ever produced by the Swedish protection experts. Its name takes inspiration from the guiding scientific principle behind the helmet's design: the Venturi effect. This scientific principle states that by constricting airflow in a choke point, the air pressure subsequently drops as it gains velocity. POC's engineers used this guiding principle to maximize ventilation by sculpting massive airflow vents in the front, which channel air inside constricted channels over the top of your head, then out from large exhaust ports along the sharp, trailing rear. By speeding up the flow of air inside the helmet, the Venturi effect means you'll remain cool and comfortable as you ride at a blistering cadence, even in the summer heat. Not only that, but the sharp trailing edges of the helmet smoothly reattach airflow coming through the helmet with that moving over the top, subsequently minimizing turbulence off the rear end, which is critical in ...

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.
