I could have built my "no compromise" randonneuring frame out of any steel I wanted. A fourty year old box of Reynolds 531 got the nod, and as far as I am concerned there is and was no better choice for the bike. Except that SL, SLX, Kaisei 022, or True Temper Verus all would have been identical to it.
