The idea of many companies is to move manufacturing bases overseas with the aim of achieving a high profit structure, but from a creative perspective, the fact that there is always a manufacturing site near an idea creates a wealth of products. I think it is very important for that. Some people are still thinking about making things in the small country of Japan.

Nitto / NITTO is a manufacturer that Japan can be proud of in the world. Based on traditional technology, we make full use of metal processing and welding to produce excellent products such as bicycle handles, stems, and carriers that we cyclists can use with peace of mind for a long time.

The NJ-89 ahead stem is a stem developed for girls Keirin.
Of course, it is NJS certified.

It is an ahead stem that has cleared the NJS standard, which is said to be the strictest in the world. Unlike men's bicycle races, Girls Keirin, which is allowed to use ahead stems, is effectively the only NJS certified stem.

It is forged from aluminum and has high strength. It is for girls Keirin, but of course it is safe for men to use. It's perfect when you want to build a classic track bike with an ahead stem.
