Casco Diamor Mountain

Our review

A versatile if slightly heavy helmet suitable for all types of riding
Skip to view product specifications

On the track, Casco helmets are commonly seen being sported by Olympic champion Sir Chris Hoy. The Diamor Mountain is no lightweight, but is a good option if you want one helmet for a mix of on- and off-road riding.


The removable peak is positioned well, shielding your eyes from the sun and the hazards of mountain biking, while the 26 vents ensure a cool ride and the metal mesh keeps bugs at bay.


There’s a large rubberised dial at the back for fit adjustment, which we found easy to use even with thick winter gloves, but the action isn’t as positive as some.
