Well done.My handlebars have done about 21,000miles, they were carried over from the frame I broke mentioned earlier in the thread.

Does anybody change their handlebars from fatigue concerns ?On the other ... we expect to get more miles out of frames than handlebars [think the manufacturers recommend changing every few years IIRC?]
Only with carbon bars (my view) but dont even know any one who has ever changed alloy bars over fatique issues?Does anybody change their handlebars from fatigue concerns ?
In well over 50 years of owning bicycles I have never done or even considered this.
The bikes I use for training get ridden and (quite literally) thrown around very hard. Ive seen one complete failure on a students bike, and plenty with early warning cracks in the finish on other bikes, so I replace them every 2nd year. A lot of MTB racers do the same.Does anybody change their handlebars from fatigue concerns ?

Back in the 90s I crack detected (whiting and dye) a par of 20ish year old Cinellis and the stem, the results were pretty shocking, especially from the stem. Since then I change the bars every 10-12 years and use a steel stem if I can.Does anybody change their handlebars from fatigue concerns ?

People are happily riding refurbished 1960's bikes with all the original alloy components cleaned up and working perfectly.
... and I've seen someone break alloy bars at 2am. Not "racey" lightweight jobs either.People are happily riding refurbished 1960's bikes with all the original alloy components cleaned up and working perfectly.
You mean steal might rust, and if it does so to a sufficient degree then it might fail. There are sufficient century+ aged frames in regular use to suggest that it is far from a fait accompli.Btw, what's all this thing about steel is for life? It rusts and will fail.
Aluminium does have a fatigue life but I would imagine a Spesh Allez' fatigue life is beyond anything a human can put it through (it ain't like those old airplanes that used to fall out of the sky due to fatigued rivets).
Btw, what's all this thing about steel is for life? It rusts and will fail. Aluminium does corrode but it bubbles over at the corrosion point and so there is no weakness that occurs.
In other words, I'd imagine an alu frame is for life and a steel frame could be.
