The Las Chronometro is a time trial aero helmet that benefits from the added aerodynamics of a clear or yellow detatchable visor to help reduce drag. The interior is made of coolmax and is removable and washable. The Las Chronometro comes with a velcro neck guard system for extra safety and is supplied with a helmet bag.

As with the LAS Istrion road helmet the Chronometro fits most sizes with its adjustable fit for 54 - 61 cm.
