anyone know anything about 731/731OS? Is it like 631 but even stiffer/harder?
I know reynolds do a touring version of 631 which has slightly thicker walled tubes for load carrying. I believe some track bikes are/were produced from this as its improved strength pressumably also makes it well suited to velodrome use. Think it might have been called 731, but I'm not sure TBH.
