Frequently asked questions
Our staff are well-known for being the most friendly, knowledgeable and professional bike experts, and will help you with any questions you may have. Here are some of the most common:
What size helmet should I buy?
A well-fitting helmet should be snug but not uncomfortable. To determine what size you’ll need, simply measure the circumference of your head using a piece of string placed about 3 cm above your eyebrows. As a guide, you can start with the below for the Azur L61, one of our most popular helmets:
| Size | S-M | M-L | L-XL |
| Measurement | 53-56cm | 55-59cm | 58-61cm |
Always check the sizing for an individual helmet under the Details tab on our pages, or check with one of our bike experts.
What is MIPS?
Multi-directional Impact Protection System (MIPS) is designed to reduce rotational motion that occur due to certain types of impacts. By allowing the head to move inside the helmet, the amount of harmful rotational motion is reduced. You can spot a MIPS helmet by the yellow liner beneath the pads when you look inside in the helmet.
