The Notch helmet from Mavic caps off their 2013 trail/enduro range of kit. It offers unique styling and a healthy amount of airflow, all at a reasonable weight of 319g (for our medium size).
The dropped rear means better protection and goggle compatibility, ideal for enduro racers. The sturdy peak is fixed in position but does sit just about high enough to remain out of sight when riding.
The 18 vents and deep internal channelling do a good job of keeping your head cool, while the Ergo Hold SL Retention system is easy to adjust and keeps the Notch firmly in place.
Helmet fit is subjective, but some of our testers felt unwanted pressure build-up in a couple of spots when the retention system was cranked tight enough to avoid helmet movement, especially on longer rides. The finely indexed retention dial and adjustable three-position retention cradle does help to tune some of this out though.
