| 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. |

| They caught on, but with more appropriate stainless alloys. Columbus has XCr, Reynolds has 931. Either can be brazed, or silver soldered into lugs, or TIG welded. Cinelli does mass production of the bike you're describing, minus the lugs. 304 can't be optimized to a point it'll compete with the vast range of other stainless steels that already exist. Something else will always be more corrosion resistant, or stronger, or tougher. 304 exists on price. It's quick, common, and cheap. This process makes 304 expensive, uncommon, and slower to produce. The proven concept is what's carrying value here. |

| 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. |

| ▲ | seethishat 2 days ago | parent | next [-] | | 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. | | |
| ▲ | jeffbee 2 days ago | parent | next [-] | | 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. | | | |
| ▲ | mjb 2 days ago | parent | prev [-] | | That's just not true, though. Stainless (e.g. AEB-L) is up to four times tougher than simple low-alloy carbon steel (e.g. 1095). See https://knifesteelnerds.com/2021/10/19/knife-steels-rated-by... for example. High hardness simple carbon steels do have their place in knives, but what you're saying is factually incorrect. | | |

| ▲ | adrian_b 2 days ago | parent [-] | | Strength very rarely matters in knife blades, unless you use knives as pry bars (strength determines the force required to either break the blade or cause a permanent plastic deformation of the blade, i.e. to permanently bend the blade). What matters is the compromise between hardness (good for edge retention) and toughness (required to avoid chipping). Many alloyed steels (especially with chromium and vanadium) allow a better compromise than simple carbon steels, i.e. either a higher toughness at equal hardness or a higher hardness at equal toughness. When you do not specify simultaneously hardness and toughness, simple carbon steels may seem good enough, because they can be made to be either very hard or very tough. If you cut only very soft things, like fish meat without bones, a very hard carbon steel blade (like a traditional Japanese yanagiba) will not have any disadvantage versus an alloyed steel blade. When you want a more versatile knife, an alloyed steel blade will be superior. |

Your chosen steel has toughness but it lacks in actual strength. |

| Now that I have an aluminum bike I can’t go back - lugging it up and down stairs is so much nicer. |
