Visor an aerodynamic problem?(7 posts)

Visor an aerodynamic problem?aliensporebomb

I've got a Specialized Enduro Pro helmet which comes with
a detachable visor.

I've been wearing it with the visor just to keep the sun
out of my eyes on days I forget my sunglasses.

I read Packmeat's advice to our promising newbie and he said
"You're an aerodynamic nightmare....lose the visor".

Now I'm thinking I've ridden over half the season with the
thing installed not realizing I've potentially had a
disadvantage as far as aerodynamics goes.

SO it's not just a "roadies don't wear visors because they
aren't cool" thing, it's a "roadies don't wear visors
because they aren't cool and they aren't aerodynamic thing."

Makes sense.

Literally! If you think about it, any extension to the helmet requires you to lift your head a little more to see the horizon. My neck and shoulders get plenty tight from holding my head up. I just keep the visor off, road or mtb, unless I know it's going to be a day in sun with little shade on the trail.

I welded a piece of sheet aluminum on my helmet as a visor. While decending the Col du Galibier, a 30 mph wind gust ripped across the road. My visor caught the gust, like a sail, and it ripped my helmet, along with my entire head, clean off of my body.
At least I don't have to wear a helmet anymore.

I insist on wearing a visor. I just don't like having the sun in my eyes, even if I'm wearing sunglasses. I simply don't trust any eyeglass to sufficiently block out the sun's damaging rays. I stick the visor to my road helmet using velcro. If it flies off in the wind, so be it. I have enough velcro on my helmet to make the visor fully adjustable. Thus it never obstructs my vision.

I think it was last year that I read that the helmet visor kills aerodynamics and I think it was on John Cobbs website. But I can't find the article now so I guess you'll have to take my word.
