Take the compact design of the award-winning Grace helmet and integrate a LifeBEAM sensor within the existing head band to monitor your pulse rate and calories burnt. The sensor communicates with a processing unit built into the back of the helmet that can then transmit data to most modern communication devices with ANT+ or Bluetooth removing the need for a chest strap and building it into the helmet you would wear anyway. This ever-popular helmet also has all the top features and great venting of a pro helmet. Rollsys is Lazer's very own award-winning fit system: simply control the size and the comfort by turning the wheel on the top of the helmet. The Rollsys system permits an accurate and progressive peripheral sizing adjustment. The fit of the helmet will be symmetrically tightened up without any pressure points on the head, with a simple one-handed adjustment. By taking away the retention system at the back the Rollsys system is also the perfect solution for people with a ponytail.
