Bontrager Lithos helmet


Bontrager Lithos MIPS helmet review


Price as reviewed:


When we tested the Bontrager Rally helmet we raved about its fit, praised its good looks and extolled the virtues of its goggle-compatibility (yes, we’re total fashion victims).

Like the best lids, the Lithos is fitted with the MIPS Brain Protection System. This adds around 30-40g in weight but the Lithos is still 100g heavier than average due to the slightly burlier construction.

It’s in-moulded, bottom wrapped on the lower edge, and also gets reinforced forehead vents with integrated sweat drainage.

It has an adjustable peak which swings right out of the way, so you can easily park your goggles underneath, but you do need to loosen the fixing screws to do this, and they’re a little hard to access with the helmet on.

A Headmaster retention device uses a one-handed dial to adjust the fit and can also be adjusted for height, albeit across a narrow range. You can attach a GoPro, or one of Bontrager’s Mini Ion lights, to the helmet using a clip-in mount.

Venting is average, but the Lithos is super snug and secure. It’s also incredibly tough.

If the worst does happen, both Bontrager lids boast an excellent free crash replacement service for the first year, too. In summary, the cheaper (£69.99), lighter Rally remains our pick of the Bontrager helmet line.
