Roc Loc 5
After more than two years of development, Giro introduces the new Roc Loc 5 fitting system.This groundbreaking system sets new standards in comfort, adjustability, stability and weight.Roc Loc 5 makes adjusting a breeze, with the dial easily locking in micro-steps in either direction. Simply loosen or tighten the adjustment with two fingers, all this is also possible without any problems while riding.Great importance was also attached to the weight of the system, it is 40% lighter than the previous Roc Loc 4.

A Micro Adjustment Dial
The heart of the RocLoc5 locks into place in micro-steps.It is easy and precise to operate with just two fingers in either direction

B Three-Position Vertical Adjustment
The vertical adjustment of a helmet has never been easier. The RocLoc5 can be adjusted 15mm in height in 3 steps, even while the helmet is on the head. This allows for perfect adjustment in the height and tilt of the helmet.

C Ergonomic arms
The ergonomic arms are shaped to ensure maximum comfort and best fit.

D Dual Pods
These guides hold the helmet firmly and in the correct position on the head. Even with smaller and larger impacts, the helmet does not slip.

In-mold
This manufacturing process permanently bonds the impact-resistant, outer helmet shell to the EPS inner foam. This reinforces In-mold helmets in critical zones around vents and on ribs. Lighter, cooler and more resistant helmets become possible.

Roll Cage
A support frame made of carbon composite material runs through the entire helmet and around the vents. This makes the helmet incredibly strong and secure without sacrificing weight.

Wind Tunnel
Wind Tunnel ventilation is Giro's proprietary system of internal ducts and active vents that channel cool fresh air over and around your head, forcing out exhausting heat and stale air.
