This helmet is designed for cycling use only, including competition. It is not suitable for motorbike use.

It is possible to adjust the size of helmets by changing the internal foams. For example, if you want a size smaller than S, you can opt for XS foam. Conversely, to obtain a size slightly larger than M, you can use L-shaped foams.

Please note: there are three different shell sizes (XS-S, M-L and XL-XXL), so foams are only compatible within the same shell size.

Size guide :

S (55-56cm) and M (57-58cm)
