Zinn & the Art of Mountain Bike Maintenance: Lennard Zinn, Todd Telander: 9781934030592: Amazon.com: Books
I was looking through "Zinn and the Art of MTB Maintenance" and came across this on p. 262:
"Do not look at the handlebar on your bike as a permanent accessory. All aluminum handlebars will eventually fail. ... Some manufacturers recommend replacing stems and handlebars every four years. If you rarely ride the bike, this is overkill. If you ride hard and ride often, every four years may not be frequent enough."
This surprised me a little, but it makes sense in terms of material fatigue I guess. The "four years" number is pretty much useless; riding hours would be a lot more useful.
Thoughts? Any anecdotes of bars or stems breaking?
