Default Handebar broke off - nasty cash

Folks,

Had a nasty crash about three months ago. Long story short my handlebar
broke without any warning. There was no cause such as a speed bump or
pothole.

http://analogconsultants.com/ng/bike/Handlebar1.jpg

The handlebar was not cheap, an ITM Mondial. It seems they botched the
design in that they used a non-coated steel stiffener tube in the
center. This corroded the aluminum from the inside out, interestingly in
riding direction. Possibly because that's where the headwinds are
hitting it and maybe cause condensation:

http://analogconsultants.com/ng/bike/Handlebar1.jpg

Luckily it didn't happen 1/2h earlier where I was coming down a steep
hill at more than 40mph, with a rocky drainage ditch. It happened at a
leisurely travel speed of 15-17mph. Thanks to the fact that it was a
very wide bike lane I had space to roll and at the end I skidded to
avoid traffic. In the lane I'd have crashed into the path of vehicles.
About the only body part that wasn't hurt was my head, thanks to the helmet.

http://analogconsultants.com/ng/bike/Helmet1.jpg

I am back in the saddle. I no longer trust aluminum and certainly not
any kind of plastic stuff so the road bike now has a flat steel MTB
handlebar. Put MeetLocks ergo handles on it, rides nicely.

As a side note I cycled by the crash site a week ago. I still saw the
scrape marks on the asphalt and debris from my bike which I cleaned up.
Interestingly all the blood was gone. Maybe a wild animal has licked it
clean.

Well, I'm glad to hear you're O.K. I broke a modern (2006-ish) Cinelli bar in the same place after less than three years in service, but it happened relatively slowly. I thought the brake lever clamp had slipped but realized my lever was moving because the bar was breaking off. I rode the rest of the way to work with one-sided bars, holding on to the dangling broken section. No crash.

I'm still riding with aluminum bars. They are generally safe. And don't think that steel is going to save the day.

Thanks. Not fully recovered but 99%. The left foot still hurts when I
wear enclosed shoes. But I usually don't in summer so it doesn't matter
much.

In hindsight I was lucky even with the crash. To get out of Cameron Park
to the west without using a busy two-lane county road you have to cross
a hill. The descent is very steep and cyclists tend to "let'er rip",
going down there at well over 40mph. So did I. Since the crash I don't
do that no more. There is a drainage ditch with boulders to the right
and it dead-ends into a busy road at the end of that descent.


I'm still riding with aluminum bars. They are generally safe. And
don't think that steel is going to save the day.



That looks like a very cheap handlebar. I mean something serious for MTB
use. That's what I have on it now. It's heavy. Not having a dopbar took
getting used to, might cost me a few minutes on longer trips. Though I
never spent much time in the drops.

Amazingly three car drivers stopped immediately and almost got into an
argument about who gets to bring me home, despite the bleeding. A fellow
immigrant drove me home. Almost new car, quite fancy, he just turned the
floor mats around in case of blood. He had a nice bike in the back and
put mine on top. Couldn't believe it. There are a lot of good people in
this world.

What surprised me was how much muscle and power one can lose in two
months. My avg speed down in the flatlands dropped from 15-16mph to
almost 12mph. Creeping back up and now at 14mph but that took nearly a
month. I still feel like a slowpoke.

Very sorry to hear of your injuries Joerg. Let me again mention a product called Second Skin that does a remarkable job of speeding healing and reducing pain.

Also again, Trek through Bontrager is presently making a helmet called "Wavecell" where the padding, instead of Styrofoam is a three-D printed padding.. The original documentation stated that it provided 28 times more protection against concussion but the latest documentation now says 48 times. Being printed it is easily changed so perhaps that wasn't a writing error but actual improvement. A helmet cannot save your life, but it could make your life a whole lot easier if you avoid a serious concussion like I had.

I have looked at tests of aluminum and carbon fiber bars. Properly constructed, the carbon fiber bar has almost infinite fatigue resistance whereas an aluminum bar does not. Strangely enough a steel bar is even less if it is stressed in the fatigue zone. The problem is that usually steel or aluminum will bend in a collision whereas carbon fiber will break.

Watch yourself. We can do without losing members of this group that have good sense. We're so few.

beings, sure.
