|Meet the Warakin. It is austenitic stainless steel.|
The thing in question is the frame material this bicycle from Otso Cycles is made from. It is a frame made from stainless steel. The bike is called the Warakin. The steel it is made from is not only stainless, but it is a certain kind of stainless.
I remember seeing the press release for this model from Otso Cycles and seeing an image of the frame tubing sticker. It had "Austenitic Stainless Steel" printed on that sticker. I laughed. I thought someone got "Authentic" spelled wrong. Well, the joke ended up being on me. You see, there are actually three kinds of stainless steel, and Austenitic Stainless Steel is one of them. (Click and learn, my friends. Click and learn) I had no idea before I saw this sticker that there were three major groups of stainless alloys. The internet sometimes really is the "information super-highway" and not always the "Info-tainment Super-Highway". Who knew?
Well, now I know! Anyway, stainless steel frames were ballyhooed a few years back and were said to be the "next big deal" in bicycle frames. Stainless (I checked and it seems that the big promoter in this was a maker of martensitic stainless steel), was supposedly lighter than Titanium and stronger than typical steels used in bicycle tubing. But then I never heard a lot about stainless frames until Salsa Cycles made their Vaya Travel. I thought that frame was rad, but I never did end up getting one.
So, anyway, all that to say that this bike is one of the rare ones out there made from stainless and as far as I know, the only "austenitic" stainless steel one. At least, the only one advertised as such.
Ya learn something new everyday........if you have an open mind!
