The Selector sees a complete revamp in Giro’s approach to TT lids with a new customisable set up that is more user friendly to different riders and positions. A removable lower back section allows you to swap rear caps to gain the best aerodynamic advantage relative to you ride position. Two of these caps come in the box; one 45mm tall and a 10mm, so you can try to get it close to your back for best possible advantage.
Inside Giro’s new Roc Loc TT retention system makes life easy with its leaf spring style design. Simply set the tension beforehand and the leaf spring will self adjust to your head. This does away with fiddly dials saving precious time out of T1. The system also has three fore and aft positions which allow for up to six centimetres of adjustment.
Up front Giro has fitted a form fitting visor which smoothes the airflow around the face and helmet for a faster ride. Small ventilation channels at the top not only reduce fogging but align with deep internal channels offering surprisingly good airflow across the head for ventilation. This can be removed if you prefer to run glasses and want to increase ventilation.
With the visor fitted the Selector is not particularly quick to get on because it’s a tight squeeze, especially as the sides are less flexible than its predecessor, although, aero advantage on the bike makes up for this.
