Bar Failure?
 

[Closed] Bar Failure?

I was told by a trail guide that he swapped his bars and stems yearly to avoid fatigue failure.

He, obviously, rides infinitely more than I do.

I've never had problems with bars, be they carbon or Aluminuim but did retire a carbon bar just because it looked shonky.

Anyone have bars 'just snap' on them? If so, light carbon / cheap ally / old / new?

Had a steerer snap and bent / cracked 2 seat posts over the years. No bars yet.

I buy new every 2 years or so for the big bike and then swap the components down the fleet to bikes that have less abuse.

My commuter is actually getting quite nice now...

I bent a fairly well used Answer Protaper like a banana last year, and tbh was really amazed- they're tough bars. So it could have been that.

I snapped a bar once years ago (Old Kona Cindercone - original Kona alloy bar). I fell of whilst messing around on a pile of canal lock gates of all things, and they must have fractured. They snapped about a mile down the tow path whilst about ten miles from home. Cycling home with half a bar still in the stem and the other half waving around in my hand trying to use the brake was amusing! I remember reading shortly after to spline it back together with a stick as a rough 'get you home'...
All in all - lucky it wasn't on the road/downhill/too fast etc.

Probably he is a bit dim.

I had some bars snap on me at speed a few years ago. One of the scariest experiences I've ever had on a bike!! Really rattled me because I didn't expect it at all. One minute I was skimming over rocks the next I was tumbling with a length of sharp edged metal in my hands.

Since then I've preferred to spec slightly heavier bars, take care not to overtighten them and to check them regularly for signs of damage. It's one experience I'd be happy not to have again I can tell you!

Snapped an alloy bar on a Carrera, years ago. Fully rigid and I did do stupid things on it all the time. When it snapped, I had just landed a small bunnyhop off a tree root. Didn't fall off - God knows how.
