Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

A question for all those who feel that aluminum bikes are inherently more prone to failure than steel bikes.

Do you Fly? I don't mean by flapping your arms, but in ALUMINUM airplanes.

There is nothing wrong with aluminum bicycles, if they're built right, and set up correctly.

Usually when I see seat tube failures, they're not because of the material, but because the post wasn't inserted deep enough (1" below the bottom of the top tube. This kind of failure is relatively new, and the result of a design change where the tube extends above the top tube, rather than ending at the seat cluster.

There's nothing wrong with extended seat tubes, but they require extra attention to seatpost depth.
