I wish someone like Columbus/Reynolds/Tange could catch on this. It'd be awesome a road bike made of fancy/extra durable stainless steel tubing, lugged, horizontal top tube and that classic geometry but with disc brakes and thru axles.

Why though? Cr-Mo steel tubing is already superior to 304 stainless in every relevant measure, except surface corrosion. In particular this article discusses fatigue behavior, and Cr-Mo has a (much) higher fatigue limit than 304.

This is also true WRT knife steels. Old, simple carbon based steels are much stronger than most stainless steels. They tend to bend rather than chip or break (when abused). They do rust and do have less edge retention than some stainless steels (such as S90V), but otherwise they are generally stronger.

Totally. Just curious why the above wanted a stainless bike. If you want a steel road bike with disc brakes and thru-axles you can absolutely order one right now. I myself ride a Soma Wolverine with Tange Prestige Cr-Mo tubing, flat mount disc brakes, and thru-axles.

If you wanted a bike that didn't necessarily need painting, you can order a bike like that in titanium tubing instead.

Thanks for that - Titanium bikes look amazing when bare metal.
