Can any of you explain the diffrence between the various steels used for
bicycles and their comparitive advantages? Example: A Lemond Zurich (DF)
boasts a Reynolds 853 sticker on the frame. It seems as though all of
the steel recumbents are 4130 chromoly. Thanks in advance.

853 has a higher strength to weight ratio, has better fatigue strength
and stiffness (about 30% greater than 4130). 853 is still Reynold's best
steel. The joints actually gain strength as they cool. 853 cannot be
brazed, only welded.

Reynolds makes a 4130 called Reynolds 525. It's a general all-purpose
tube - less expensive than 853.
