Grant Petersen the founder Rivendell, and a great friend of Nitto gave the most accurate description of Nitto in Rivendells's catalog back in the day.
Nitto is a small, old handlebar-stem-seat post-rack-and bottle cage maker in Tokyo. and everything Nitto makes is the best of whatever it is. The designs are always spare and beautiful. Nitto's company slogan is "Light weight, heavy duty, finely made." and it is accurate. There are lighter seat posts, but Nitto's are light enough, and stronger. Nitto will not build anything to its customer's specs if it doesn't pass Nitto's own internal standards.
Nitto can bend metal in ways that other makers just plain can't Mr. Yoshikawa, who designs most of Nitto's products, has an eye for beauty that, in my experience, is unmatched. He takes our ideas and rough sketches, and turns them into stunnigly lovely shapes -- the Moustache Handlebar, the Noodle Bar -- and he test the heck out of them to make sure they're safe.
There aren't many companies like Nitto these days, and none other that I'm aware of making bike parts. It is a pleasure and an honor to offer them to you. Every loved bicycle deserves some kind of Nitto on it.
