POC Ventral Lite Road Cycling HelmetLight. Protective. Fast. The POC Ventral Lite Road Cycling Helmet has been developed to be all three. When low weight but high protection is your goal, this is the helmet to choose. Weight x SafetyPOC started with their renowned Ventral Air helmet and through careful engineering have been able to save overall weight while also making the Ventral Lite Road Helmet more rigid and preserving the excellent crash protection of the original. The Polycarbonate shell is also lighter, covering less of the liner to keep the weight as low as possible. This same minimalist approach is also applied to the straps and adjustment system to shed yet more weight. Coming in at a svelte 200g (medium) you'll barely notice it's there. POC ProtectionDespite the drive to minimise weight you can still be confident in the head protection the Ventral Lite offers. The EPS liner features multi-density zones to deliver targetted head protection should you crash. As mentioned above, a polycarbonate unibody shell is placed in key areas to enhance safety and helmet integrity as well as durability. The straps are also anchored to the helmet for a greater degree of hold in the event of a crash. Lastly, a lightweight size adjustment system makes adjustment easy and keeps the helmet locked in place, vital should you take a fall.Fast and CoolThe Ventral Lite has the same focus on smooth airflow and excellent ventilation as its Ventral Air sibling. The efficient vent design and internal air channels are the results of CDF analysis. Minimal air turbulence keeps aero performance high, while precisely placed intake and exhaust vents suck air through internal channels, turbocharging the cooling performance of the helmet. Whether it's a high-speed ride on the flat or toiling up a hot climb this precision venting works to keep you cooler and sweat-free.FeaturesInternal channels control the airflow at high and low speedsExtreme cooling and ventilation thanks to innovative internal airflow designCFD-tested design minimizes turbulence and enhances aero performanceOptimized EPS liner for low weight and crash protectionWrapped unibody shell enhances the helmet's structural integrityLightweight 360-degree size adjustment system makes it easy to find a precise fitAdjustable straps anchored to the helmet linerEye garage keeps sunglasses secureWeight; 200g (M)CERTIFIED EN 1078, CPSC 12.03, AS/NZ 2063Buy POC Helmets from Chain Reaction Cycles, the World's Largest Online Bike Store.

Accurate heart rate monitoring & Integrated GPS Long battery life: up to 30 hours of training time with GPS and OHR Training Load Pro & Running program Fitspark training guide Nightly Recharge sleep tracking Fuelwise & Energy Sources Weekly summary Music controls, Weather, Phone notifications, Customisable watch face Using real-time heart rate data during your workouts means you have instant insight into how your body is responding. This means you’ll be training smarter, which is always better than simply training harder. Frequency: How many times you exercise during a period of time, for example per week. Duration: How long you exercise at a time, usually counted in minutes. Intensity: This one is a bit more complicated – and that’s where your heart rate comes in. Your heart rate is one of the best indicators of how hard your body is working during training. Instead of trying to ‘guesstimate’ the intensity of your workout, your best bet is to rely on your heart rate which is a trackable number, just like frequency and duration.
