Bontrager Quantum helmet review
Bontrager’s Quantum helmet doesn’t really fit into any specific category, being suitable for cross country and trail riders on a budget. Indeed, the ‘Visibility Yellow’ design we tested is also prime for commuters.
The Quantum offers great value for money, and certainly feels like a pricier item. Bontrager has a one-year free crash replacement policy too. The 347g weight, while not spectacular, shouldn’t be sniffed at. The quality of the materials used is good, especially the retention system.
However, the retention system did provide our main niggle with the Quantum. The plastic arms along the side, which include rubberised panels, are too low, and rubbed on the tops of our ears. Adjusting the cradle vertically helped, but it still occurred, especially when we were wearing our sunnies. Adjustment of the system is through a plastic wheel on the back that needs pressing into the head for it to turn. It’s not the most tactile.
Despite our retention niggles, the rest of the Quantum is good. Fit is comfortable, the padding placed in just the right areas with no strange internal EPS shapes. It’s also a relatively cool lid too as the vents are well placed to direct air over the head. Out front the visor is removable, but not adjustable. It’s not too long though, and never got in the way of our vision.
