When you buy a $500 helmet

At that speed going uphill I take my helmet off.

Good idea… we’ll test this next time!

Glad the test wasn’t lost on everyone, though. I think the use of 40kph as the quoted speed was my error. I could calculate the watt difference at 20kph using the same CdA data, but no matter how I spin the maths, our test showed you save time by not putting your sunglasses in your vents. Plus you’re not closing them off and stopping airflow, which can only make things hotter.

Given how often I see pro riders doing it, often when in a mountain breakaway, I wonder whether it’s something teams have ever thought about / tested.

I miss the days of doing that…but between the size of current bike computers, the out-front mounting style, and oversized stem / bars, my helmet straps are not long enough anymore to out my helmet on the front of the bike. :man_shrugging:t2:

UK folks the Decathlon FCR Mips in black is back in stock, I’ve just put my order through

Any data no Specialized helmets? I find their lineup confusing now. There’s the ARO5 race (which I would expect to be their aero helmet because of the name), the Evade III (which is the real aero one?), the Prevail (which is more all-around) and now the even more confusing Propero 4 (where does this one sit in the list?) @joshcroxton did you manage to get your hands on the last one? I think it’s the newest of the bunch and they claim it’s as aero as the evade but as airy as the Prevail… I might consider paying to get behind the paywall if that info is out there :wink:

The ARO5 is an Oakley helmet, not Specialized.

Oh you’re totally right, I got confused by my LBS carrying all those. Thanks for the correction!

I have been using the Propero 4 lately, but it didn’t arrive in time to make our test, so no data I’m afraid.

General quick review: it’s a decent second-tier aero-all-rounder. It’s definitely more Evade than Prevail, but it feels/looks a little bulkier on the head, and uses a plastic mips liner rather than the nigh-on invisible Air Node. It’s not as airy as the prevail imo (nothing is).

Hope that helps!
