Giro Selector Aerodynamic Time Trial Triathlon Helmet

Giro unveiled their newest aerodynamic helmet, the Selector, for Saturday’s Giro d’Italia time trial. Intended for Time Trials (and possibly Triathlon), the Selector tops the Advantage model to become their premier TT helmet.

The Selector includes an integrated visor and interchangeable rear panels that allow the user to fit it to their shape and riding style. Also introduced is a new Rocloc TT retention system designed specifically for this helmet. Two lowers will come with the helmet, one 45mm and the other 10mm, to minimize the distance between the rear of the helmet and the rider’s back, whether it’s flat or rounded, in a low position or more upright. Underneath the lower rear panel, it’s completely closed off and smooth to prevent air from getting trapped underneath as it flows over the shoulders and around the neck.

The visor has two vents near the top that align with internal channels to help vent fresh air in and around the head, exiting through two large ports in the back. Giro says they’re also there to prevent fogging. The included lens has a gray tint, but a clear one will also be available, and it’s removable for those that prefer (or are contractually required) to wear another brand of shades. Obviously, maximum aerodynamic benefit comes from using their visor.

Giro Selector Aerodynamic Time Trial Triathlon Helmet Color Options


In addition to team edition colors (not sure if those will be offered aftermarket), it’ll be available in four standard colors, including that brain melting but totally awesome looking solid black.

Giro Selector Aerodynamic Time Trial Triathlon Helmet with RocLoc TT Retention System

Because the rear panels are totally enclosed, Giro needed to design a new retention system. Enter Rocloc TT, a leaf spring-tensioned system that puts a preset amount of pressure on the rider’s head. This setup eliminates dials or ratchets and, Giro says, speeds up putting it on, something Triathletes will appreciate at T1. Other features are:

  • Fixed webbing like the Prolight with adjustable chin strap buckle
  • Thermoformed SL Roll Cage internal reinforcements
  • Removable EVA side pads to customize width
  • X-Static antibacterial pads
  • S/M (385g) and M/L (418g)
  • Available in June for $275 (£240)


  1. shouldn’t this product have come out a long time ago according to UCI rules?
    its been used for what about 3 years now by pro teams, UCI needs to start actually enforcing rules evenly like that one if they ever want to keep looking legit.

  2. The pro teams started using ‘these’ helmets less then a year ago. For example Lance Armstrong got a custom fit helmet. I am afraid the UCI will ban these helmets, since the lower part seems to be there only for aerodynamic reasons, which isn’t allowed.

  3. I think you should have to show your UCI Pro license before buying one of these. Because exactly ‘nobody’ needs this. Fancy bike parts are one thing, but a dorky (dorkier?) helmet to help you go faster is really beyond any amateur necessity.

  4. Gillis, aero helmets have actually been shown to be one of the most effective ways of improving your performance in time trials (yes, even for amateurs). They’ve been shown to have a far greater effect than those $2000 wheels that are becoming so ubiquitous. Compare that price to the $200 or so that an aero helmet costs, and it almost becomes silly not to get one if you race amateur TTs.

  5. Nobody “needs” a Porsche 911 either or a Rolex or a Gucci purse but people want this stuff because they appreciate style, performance, status and have the money or credit to buy it. Now, should they direct that disposable income towards something more practical and use the savings philanthropically? Maybe so but then Giro doesn’t sell the helmets and has to lay off workers, their competitors fill in the gap by offering aero helmets which establishes their dominance in the category which drives their sales across their range and Giro loses more market share and lays off more workers who are showing up at the soup kitchen in droves. The moral of the story is buy a dorky new helmet now or buy someone a cup of soup later.

  6. So the amateur gets the helmet, moves up several catagories due to a mechanical advantage, is now with a group where others have the same helmet (or better) and all of a sudden isn’t so good.
    Now he (and really it is He, because even fewer women are going to buy this) gets depressed and goes postal at work stabbing his co-workers with the backside of his helmet.

    If you’re relying on a helmet to do better, then you got your head between the spokes. Spend the few hundy’ on a trainer/coach instead–Keep your money local and actually get better.

    I’ll buy the soup.

  7. @gillis, Trust me, you aren’t going to “moves up several catagories due to a mechanical advantage”. I still get my butt handed to me from time to time from guys on old steel bikes in crits while I’m on carbon.

  8. @gillis… Don’t lose too much sleep over the guy who gets an aero helmet… Why do you even care how they spend their money (?) I don’t give a flying frig over the guy who buys a Lambo just to drive 60 mph.

What do you think?
