Giro created the Bishop for riders in search of the classic fit but in need of an extra-large size. Inspired by the sleek lines and serious ventilation of the Revel and Verona, this helmet is equally at home on pavement and dirt, and its In-Mold construction keeps it light without compromising durability. The on-the-fly adjustable Acu Dial system makes it easy to custom-tune the fit, for maximum comfort and stability.
