Cycling just got a whole lot safer with trek’s new wavecel helmet y gasset


Riding a bicycle never gets old. I’ve ridden hundreds of thousands of miles and look forward to riding many, many more. I love my bike but there’s no getting around the gas density formula fact that riding it is dangerous. Ride a bike long enough and you’ll fall. It doesn’t matter if you’re a beginner or a pro, a racer, commuter, recreational or endurance rider, riding the road, gravel or single track. You’ll fall. And when you do, there’s a good chance you’ll be injured, possibly seriously, possibly fatally. Earlier this week, Trek Bicycles introduced a revolutionary bicycle helmet that markedly reduces the la gastronomia likelihood cyclists will suffer serious head injuries.

Head injuries are among the most common cycling-related 76 gas credit card login injuries and are almost always involved in cycling fatalities. The Royal Society for the Prevention of Accidents reported in 2017 that over 40% of cycling injuries that resulted in a hospital visit involved a head injury. Moderate or serious head injuries were present in over 70% of cycling fatalities in London and electricity news philippines over 80% of cycling deaths in rural areas. Head injuries are almost certainly underestimated because cyclists fall, bonk their noggin, suffer a concussion and don’t go to the hospital.

Brain injuries and concussions usually result from the brain bouncing around inside the skull in response to two types of energy released when the head is hit. Linear energy is produced by head-on impacts. Smash your head directly into a wall in front of you and linear energy is causing your a shell gas station near me injuries. Rotational energy is released when the head hits a surface at an angle. A cyclist who hits their head while sliding along the road after a crash is an example. Helmets are designed to protect electricity definition physics against injury by dissipating both types of energy before it reaches the head.

Rotational energy is far more likely to be the culprit in injuries suffered by cyclists. It’s also much more likely to produce concussions than linear energy. Put those two together and you come up with a no-brainer. You want a helmet that dissipates rotational energy. And there’s the gas usa rub. The typical bicycle helmet that’s been in use since the 1960s does a good job dissipating linear energy from head-on impacts but is relatively ineffective in dissipating rotational energy.

The rigid foam-like material inside a helmet’s plastic shell is called expanded polystyrene or EPS. It compresses on impact and deflects linear energy before it reaches the head. Unfortunately gas national average 2008, EPS doesn’t work nearly as well mitigating the effects of rotational energy. Most of the rotational energy is transferred to the head with concussions being the most likely result.

A technology called MIPS (multi-directional impact protection system) was introduced in the early 2000s. MIPS works as a liner between the EPS foam and the helmet’s shell. The helmet slides over the liner directing energy away electricity voltage in norway from the head when the head is hit at an angle. Combining MIPS with EPS gives you a helmet that reduces injuries resulting from both linear and rotational energy—up to a point.

The problem with MIPS is that it becomes less effective as the force of the impact increases. The MIPS e seva power bill payment liner gets crushed and can’t slide when the force of the impact reaches levels electricity symbols and units that are commonly experienced in bicycle crashes. When that happens, the rotational energy that is largely responsible for concussions is transferred to the head.

This is where Trek’s new helmet enters the picture. Trek developed a new material they call WaveCel. WaveCel is a layered liner that doesn’t just redirect linear and rotational energy, it absorbs it. As the force from an oblique impact builds, the layers in the material fold sideways to different degrees which keeps the liner from being crushed to the point where it can’t slide. The result is that rotational energy is absorbed and electricity for refrigeration heating and air conditioning 9th edition answers deflected away from the head.
