    Selective speed.

    When Giro looked to up its aero game, it didn’t just paste new stickers onto its Advantage helmet. It looked at the data and redesigned it to create the Giro Selector. This helmet is now a standard in the professional peloton and should be a part of your aero kit as well.

    Giro used wind tunnel testing to sculpt a shape that works with your position on the bike to lessen the drag coefficient. On the front end, you’ll notice the eye shield. Not only does this minimize tear-inducing wind in your eyes, it also smooths the leading surface so that the air moves over it faster. An added benefit is that the shield also acts to block out excess wind noise. Two vents help direct the air through the helmet and out the back vents to cool your head. For those who prefer sunglasses, however, the shield is removable. On the other end, the tail of the Selector helmet is closed on the underside and comes in two lengths, 10mm and 45mm. Each is designed to work with your body position and the choice depends on how low your shoulders and arms are. The helmet should sit low and close to your back when you are in an aero position.

    To secure the Selector, Giro uses the Roc Loc TT system. Different from the older Roc Loc 5 system, the TT uses a spring leaf system to apply even tension to the front and back of your head in order to secure the helmet. The body of the helmet is an EPS-injected molded liner with the Giro SL Roll Cage system and a polycarbonate shell.

    A good TT helmet is aero, has venting and is the best shape for YOUR TT position. Everybody has a different position on the TT bike and there is not a "one size fits all" or "best TT helmet". Rather, the best helmet keeps you aero during the entire race.
    This means that if you are constantly looking down at your computer during the race, a helmet with a tail is going to turn into a tall brake every time you look down. This helmet has a medium length tail which means you need to be able to stay in your tucked position during the entire event, otherwise look at a stubby tail helmet like the Bambino by Kask.
    The only negative about this helmet is its lack of venting. It gets warm during a race but a lack of venting is faster. I know the description mentions that the lens "ducts a sizeable volume of cooling air to flow over the head and out the twin exhaust ports in the tail of the helmet." it really is hard to tell. I have used it in a 75 degree race (10 miles) just last night and I sweated a bit so this summer I may cook a bit!
    Overall, Yes I would recommend. Yes, I would buy again. And Yes, it performs well.

    Consider One Size Larger

    The helmet is what I consider a super tight fitting thanks to its ear protection cover. Look at the contour of the helmet you can tell it's a challenge to get your head inside, but that's where it gets its aerodynamic feature. I have to use a shallow tail to fit in. Package contents come also with a shallow tail so you get to choose. Other than being a tight fitting, this is definately a great helmet, state of the art aerodynamic design. I wore it and I am lovin' it. Yes, I am wearing spectacle and still able to fit behind the visor.
