I was just wondering if anyone has experience with an aluminum or scandium cross frame, such as those built by rock lobster? I was wondering how long a frame like this would last on average? I know steel and titanium frames are supposed to last the longest. I'm thinking of using the frame for recreational riding, but maybe i'd learn to race cyclocross some day.
For someone who wants a cyclocross bike as a commuter, recreational type bike, would you recommend getting a steel frame opposed to aluminum or scandium? I really like Kish Fabrication's titanium frames, but they're about $1000=$1500 more than the Rock Lobster aluminum and Scandium frames.
I know Aluminum and Scandium are lighter than steel, but it seems like false economy to buy a super light frame is it's not going to last for many, many years.
