Got a question you’ve been dying to ask about helmets? Whether it’s about their features, technology, safety, testing, materials, design or anything else, we’ve got Giro on the line this week to answer all your questions! Like, maybe about their new Aether with MIPS Spherical tech. Or some of the other new helmets they launched at Eurobike?

To submit a question, use this form and send it in early! We’ll be batching and sending them the questions through Wednesday night so they have time to answer them for this Friday’s AASQ column.

  1. With how few road helmet molds there are my not create a visor that can clip onto the vent holes? I realize I’m in the minority of road cyclists who love having a visor (ok, the shorter ones, not the really long ones like the chronicle) on my helmet so you can’t just make a visor version of all the helmets as the sku may not sell enough. But if you could make a visor that could use the existing vent holes to hold the visor on it would be easy to sell visors separate from the helmet. Cycling caps don’t work as they feel hotter and the brim doesn’t stick out that far.

    Sure if I just bought off the internet I’d be fine, but less then half of helmets fit comfortably so kind of need to try on first. (usually its something in the back of the helmet pressing on my skull in an uncomfortable way)

  2. Will we (consumers) ever be able to review actual helmet test data? Actuall transmitted G forces? Or will we continue to just get pass/fail results based on the industry certifications? If not, what’s the rational behind that? I’m not trying to pick on you (I like Giro), I’m asking with regards to an industry as a whole.
    For example, I like that I can see whether my car passed or failed industry crash test standards. Great. But what’s even better is that I can get an actual score of how it does in different tests and even view crash footage. White not everyone goes to the lengths to research this, I feel its important to have available so that the consumer can make the best educated decision regarding their safety.

  3. I care.
    My dollars, my choice.

    (I would like to preemptively apologize if my opinion as stated here contributes to a non productive internet forum argument)

    • Capitalism only works well when customers are informed enough to spend money where they want to spend it. Companies need to compete for that money, they don’t automatically just deserve getting it.

      • This information is hardly in any way hidden as you’re insinuating. Vista is publicly traded company and consequently this info is widely available.

    • So playing devils advocate, using your logic of not buying a helmet because the parent company also owns a company who’s products were misused to kill someone. You condone killing people as long as it is with heavy fast moving objects (cars) and addictive poisons (alcohol)? This is based on the fact that i assume you have a vehicle and have purchased alcohol.

      Seems silly when you apply that logic to basically anything else in society.

  4. Does “normal” operating temperature (i.e. atmospheric temperature) affect the performance of a helmet? We know not to leave them in a hot car on a summer day, but does riding at -10F affect the performance of a helmet? How about 90+F? Thanks!

    • I do NOT work for Giro or Bell but I would be happy to answer your question.

      Very much so. Foam softens at high temps and stiffens up at cold temps. But all bicycle helmet standards take such situations into consideration. When helmets are certified they are tested at ambient (room temperature), hot (~122 F), and cold (~5 F – ~14 F) temperatures. The helmets are conditioned at these temperatures between 4-24 hours before they are pulled out of conditioning and tested (impact must be done within a matter of minutes for results to be valid). This, combined with the different anvils used during testing creates a balancing act for the engineers and designers. They need to balance helmet foam thickness, helmet foam density, helmet shape, and vent size/shape to ensure a passing result. This is also why EPS is still used as the primary foam in helmets as it is relatively temperature stable compared to other commercially viable foams/materials on the market.

  5. Custom helmets? Thinking a two part helmet where the outer EPS foam passes the crash testing and an inner liner could be better shaped to a person’s head. Make the mips liner more custom fitting and be able to use small spacers that allow it to come closer to the head where needed.
