Either I'm not very good with the search tool or there is little written about this topic.
I'm shopping for a new ride and was hoping to get an aluminum frame with Carbon Fiber forks and CF seat stay. There have been some comments made that these materials don't last as long as cro-mo, and CF often gets stress fractures in only a couple of years.
I use my bike for exercise, I ride about 12-15 miles a day, 5-days a week, on paved surfaces. I want a bike that will last at least 5-10 years. My cro-mo hybrid Bianchi has served me well for nearly 15 years, but I'd like something more modern and a little lighter and a little more comfortable. But if these materials are not durable then I may have to reconsider my choice.
I welcome comments from everyone, but would really appreciate feedback from those with actual experience in this regard, be it good or bad.
look into a curtlo... custom steel... made just for your ass
and lightweight components can easily make up for a heavy steel frame.
For once Merton is right on the money here.
If you divide the cost of a bike like a "Rivendell" over a period of years you can own a
serious steel bike that will ride, and last, better than any aluminum / carbon fiber junk
you could spend your money on.
There IS a reason that custom builders all use steel, mate.
I can't recall anyone on bikeforums post about their frame failing due to fatigue (or whatever is the carbon fiber equivalent) regardless of what material is used in the frame. Maybe there's only a small number riding bikes older than a few years, but I doubt that.
I think it's more along the lines that frame fatigue takes a long, long time regardless of what material is used. If carbon fiber forks cracked and failed after just a few years, product liability lawsuits are going to soon put every high end bike company out of business.
Buy the bike you like and don't worry about frame failure. Most good bikes have lifetime frame warranties anyway. Just be sure to buy new from an authorized dealer if you want the warranty.
