Ben Delaney of BikeRadar rated the Tonic highly, saying that with its fit and finish, it doesn’t feel like an entry-level helmet at all…and I agree. In terms of basic fit, the Tonic fits on my head as well as the Blade does, retaining a trim, svelte form factor. Please note: Manufacturers can sometimes change the specification of the products from time to time. While it had served its purpose, the Transition was also a cheap, heavy thing with poor ventilation. We also do not accept products that are intimate or sanitary goods, hazardous materials, or flammable liquids or gases.

Most notable is the TS+ Turnfit System, which is how Lazer reconfigured its Advanced Rollsys fit mechanism into a more affordable, more generic format. At 230g for a Medium, it weighs the same as helmets more than twice as expensive, such as the Specialized S-Works Prevail or the Bontrager Velocis. The chinstrap material is a touch heavier and more inflexible than higher-end helmets, but once it is adjusted you likely won’t notice it at all.

With 28 vents, the Tonic offers lots of exposure to the air and wind, and should offer good ventilation in theory. The plastic cradle can also move up and down within a range of five steps, but it’s just as stubborn to move and is best left alone once set to preference.
