Fit, Protection and Style 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.

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. This helmet is designed and intended exclusively for use by bicycling activities, including mountain biking and off-road cycling.
