[obc] Metal life expectancy

[Perry McKenna]

Hello all,   I would like to know what is the life expectancy of the different frames material.  I have been getting conflicting info.  One book (the new Lance Armstrong) says that aluminum is only good for 5 years.  I asked my bike shop and they told me that Aluminum can fail after a while, but that it depends on how hard and how much you ride but that you should be able to get a lot more than five years.   They also informed me that steel, will also weaken after about five years(based on riding about 5000 km a year) and will no longer be very stiff after that point. I always thought that steel would last a lot longer than that.   Does anyone know the facts?   Perry    ------ To unsubscribe, send a blank message to [EMAIL PROTECTED] Club Office: [EMAIL PROTECTED] Web/mailing list: [EMAIL PROTECTED] http://www.cyberus.ca/~obcweb Newsletter: [EMAIL PROTECTED] http://www.cyberus.ca/~obcweb/Newsletter ==^================================================================ EASY UNSUBSCRIBE click here: http://topica.com/u/?aVxiDo.aVHtMM Or send an email To: [EMAIL PROTECTED] This email was sent to: [EMAIL PROTECTED] T O P I C A -- Learn More.
