Troy Lee Designs A2 MIPS 50/50

Troy Lee has done it again! Once again raising the bar, the new for 2017 A2 helmet is redefining mountain bike safety, style, comfort and ventilation. The first helmet in its class to combine EPP (for slow speed impacts) and EPS (for high speed impacts) in a sleek package that will provide riders with more confidence to ride harder and go bigger. Thirteen air intake and exhaust ports force air through the helmet to help keep you cooler and dryer. A 13-position stabilizer basket and fixed side strap anchors provide a comfortable and easily adjustable fit.

Troy Lee Designs A2 MIPS helmet is equipped with the patented MIPS system to reduce the rotational forces to the brain in the case of an oblique impact. Where most helmets are tested for vertical impacts, studies have shown that the human brain is more sensitive to oblique impacts. MIPS technology mimics nature’s own method of reducing forces transferred to the brain in the event of a crash. When subjected to an oblique impact, a membrane between the brain the skull allows the brain to slide along the inner surface of the skull, which ultimately reduces the forces transferred to the brain. MIPS helmets use a low friction layer between the shell and liner to mimic this process, which significantly reduces the forces transferred to the brain.
