Lazer Roller bike helmet The Lazer Roller helmet offers protection, style and comfort for cyclists who don't want to spend too much. With its understated design, the helmet is in its element both in the city and in the countryside. An in-mold construction keeps the weight low, while the visor offers extra protection. 28 vents keep you cool and comfortable while cycling. A dial at the back of the helmet operates a shell that protects a large part of the back of the head. A quick turn of the TS+ dial ensures a snug yet comfortable fit that keeps the helmet firmly in place. Adjust the helmet while you ride and start your cycling adventure.
