Smokin Joe said:30 or 40 years if you look after it. Why shouldn't it, as long as the builder has not taken liberties by making the tubes too thin it will not fall apart. Nobody queries how long there brake calipers will last, yey like most stuff on a bike they are alu too.
Many Jumbo jets are still in service after 30 years, and they are made from aluminium. And before anybody says it, no the don't replace the entire airframe and fuselage every couple of years in case it will fall apart.
So how many fifty year old steel frames do you see around now? Or even twenty year old, come to that.yenrod said:In this case - how have they got such a bad name/reputation ?
As in, a steel frame will last longer...

They have got a "bad reputation" because people who hate progress and can't see why the rest of us are not happy riding round on a 1955 Curly Hetchins with a four-speed block and toe clips and straps keep telling us that Aluminium will melt after two years and carbon fibre will explode in sunlight.
Fab Foodie said:I think the question marks regarding Aluminium's longevity in Bicycle frames probably stems from problems associated with welds cracking in early models. Technology is well sorted by now. One rarely hears of Aluminium frame failing these days. Steel frames can also fail as well... the difference is that steel can be repaired.
