I am very much interested in turning my old Steel Chrom double butted KHS (Crest) into a SS . Commuting and eventually trail riding. I was wandering though – Material wise, if the Steel is not to flex for SS?
Must I Look for a stiffer aluminium frame? Or maybe there Are advantages I'm missing out on this classic and xc frame design… I know there are Steel SS intended frames out there, but aren't those Extra Strong to prevent flex?( unlike my sweet KHS frame)

Any Info and Advise Are Absolutely Welcome.
