The bike industry is constantly innovating to make products lighter, faster and more aero. This is no different when it comes to bike helmets, but the increased focus on safety and third-party testing has been a most welcomed trend. 

The all-new Giro’s Aries Spherical helmet premiered today still focuses on all the 'lighter', 'cooler, 'faster' superlatives but places safety front and center. The Aries is claimed to be the brand’s lightest and airiest helmet in the Mips’ Spherical Technology line yet but also the safest with a #1 safety rating from the esteemed Virginia Tech University.

Anne-Marije Rook
North American Editor

Cycling Weekly's North American Editor, Anne-Marije Rook is old school. She holds a degree in journalism and started out as a newspaper reporter — in print! She can even be seen bringing a pen and notepad to the press conference.

Originally from The Netherlands, she grew up a bike commuter and didn't find bike racing until her early twenties when living in Seattle, Washington. Strengthened by the many miles spent darting around Seattle's hilly streets on a steel single speed, Rook's progression in the sport was a quick one. As she competed at the elite level, her journalism career followed, and soon she became a full-time cycling journalist. She's now been a cycling journalist for 11 years.
