After years of research and development, the Troy Lee Designs Team introduced the A1 mountain bike helmet in 2013. Here at TLD, styling, graphics, fit, function and safety are key in everything we create.
This lightweight, fully encapsulated all-mountain helmet utilizes maximum coverage and dimension to keep you safe and protected in all riding conditions. Whether you're charging single track, riding dirt jumps or grinding out miles on the XC bike, the A1 helmet offers the premium fit, protection and style you want.
With the A1 helmet, we at Troy Lee Designs returned to the aggressive all-mountain half shell category.
