Giro Selector Aero Helmet

My Giro Advantage 2 aero helmet never really felt quite right.  It was always tight.  I'd have to pry it over my ears and be uncomfortable until they finally found their place behind the thick flap of plastic that comprises the ear covers.  I used it with some success, I think.  I found, through my own riding that the Advantage 2 reduced my time on a 7.5 mile ride by about 30 seconds.  So, I'm a believer but I wanted more.  More comfort and more speed.

The Advantage 2 comes in three sizes, small, medium and large.  I had bought a size small Advantage 2.  My head measures 21 3/4 inches (55.245cm) at the hat band area.  That's right at the limit for a small.

The Giro Advantage 2 has 3 size options
With all the strain on the ear flaps my Advantage 2 formed a crack on both sides.  It was time to replace it!  I decided on the Giro Selector for several reasons; 1) it has an integrated vision 2) it has 2 "aerodynamic lower" options, and 3) the cost wasn't prohibitively high.  I bought mine through Amazon for less than $200.

I ordered the small/medium Selector.  My head was safely within the sizes listed on the Giro website.  When the helmet arrived it came with the items below.

What the helmet comes with
The Selector helmet comes with 2 back plate options, and instruction booklet, a cloth bag, an extra set of pads, a red "G" sticker and an emergency contact information sticker.

The Selector has no large vent holes like the Advantage 2.  It's a possibility that overheating could be a problem.  That's one of the reasons I chose white and silver for my colors.

I decided to adjust the Roc Loc TT fit system back one space to the last snap basket.  To do that I removed the Roc Loc bracket. Make sure that you look closely at the two pictures below.  The bracket has 2 snaps and 2 curved legs.  The snaps keep the bracket securely forward and the feet of the legs under the snap basket frame.

I used a shish-kabob skewer to ream out a place in the foam one space back for the legs to go into.

I re-installed the Roc Loc bracket and that was it.  I tried the newly adjusted helmet again and it fit much better.  The ear flaps still look to be a bit tight but I'm sure that I'll get used to putting in on more quickly over time.

I wore it for the first time on Saturday during a 19 mile 23 average MPH ride with 4 other guys and a subsequent 30 mile ride with 2 other guys at 21.8 MPH.  I found that my ears are still an issue.  I think a dab of BodyGlide on the ear tab pads should help them find their proper place in the confinement of the straps and foam.  The field of view is freakin' awesome.  There are no obstructions at all although looking to the side to see who's riding behind is a strain.  The air temperature was 70-degrees.  I didn't find that the limited venting was an issue.  The flow of sweat was allowed to move unobstructed.  I find with sunglasses that the sweat seems to pool around the lenses.  There was no lens fogging.  Bugs smacking into my face at 30-mph should be a thing of the past too.  That's a good thing!  The ability to hear is reduced, as I'd expect.  The ambient noise inside the Selector helmet is probably lower than my Advantage 2.  The only negative is that the interior of the helmet is not well padded.  It's like wearing a can on your head.

Well, that's about it!  Just a lot of pictures of my new helmet.

Thanks for reading.
