Are aero helmets worth the investment for cyclists?

Question

I am thinking of upgrading to an aero helmet but I’m not certain it is justifiable. What kind of difference is an aero helmet going to make in terms of watt savings if any?

Answer 1

If you are a triathlete, it may make sense to invest in an aero helmet as it can save you a significant number of watts depending on the model and your riding position. Time trialists' helmets have little aerodynamics but can save 30 or more watts and some aero road helmets save 12 to 15 watts. Many also have fewer vents which may result in more aerodynamic properties. Several other models of aero helmets even permit altering the vents in order to enhance aerodynamics at different stages of the activity.

Dylan, what I would love to see is content on how to train to ride in an aero position for longer.

What kind of stretch exercises, strength exercises and on the bike drills I could apply so that I could actually hold my aero tuck for a long time.

I feel as when I’m fresh I can usually hold an aero position for a while, but as I get fatigued my triceps start burning, shoulder gets tense and It becomes hard to hold the tuck.

Thanks for the awesome content as always

Triathlete here and for us aero is everything. On a road bike not so much because the biggest gains is in your position and you can only do so much on a road bike but that being said a helmet, assuming it works with you position can save  a lot of drag but clothing is probably the biggest benefit. Aero road bikes are the least bang for your buck. The rider is the real drag. Not the bike.

Thanks Dylan - as usual, hugely informative and, totally gripping.
