NITTO NJ-89 Girls Keirin Stem
Many companies are shifting their manufacturing bases out of Japan in order to become more profitable, but from the standpoint of creativity, I think it is very important to always have a manufacturing site close to the idea in order to create rich products. There are people who still want to make things in this tiny country called Japan.
NITTO / NITTO is such a manufacturer that Japan can be proud of in the world. Based on traditional techniques, NITTO uses metal processing and welding to produce excellent products such as bicycle handles, stems, and carriers that cyclists can use for a long time with peace of mind.
The NJ-89 Ahead Stem was developed for girls' keirin.
Of course, it is NJS certified.
The NJ-89 Ahead Stem has passed the NJS standards, which are said to be the strictest in the world. Unlike men's bicycle racing, the NJ-89 stem is the only NJS-certified stem for girls' keirin, where the use of a head stem is allowed.
The NJ-89 stem is made of forged aluminum for high strength, and although it is designed for girls' keirin, it is of course safe for use by men as well. This is the perfect choice for those who want to build a classic track bike with an Ahead stem.
