Nitto NJ-89 Stem

No, this stem is designed specifically for track cycling and requires handlebars with a 25.4mm clamp diameter. Most modern road handlebars use a 31.8mm clamp, so you will need to verify your bar size before purchasing.

No, the NJ-89 features a traditional single-bolt clamp design without a removable faceplate. You will need to slide your handlebars through the clamp, which works best with track drops that have a specific bend profile.

NJS approval signifies that the component meets the strict safety and quality standards required for professional Keirin racing in Japan. It is a mark of high-level craftsmanship and durability, ensuring the stem can handle the intense physical demands of track cycling.

Yes, the -17 degree drop is quite aggressive and is designed to put you in a lower, more aerodynamic position. It is ideal for track riders looking to optimize their setup for speed, but it may feel significantly lower than a standard road stem.

While it is built to withstand the rigors of the track, its aggressive geometry and lack of a removable faceplate make it less convenient for a daily commuter. It is best reserved for fixed-gear track bikes or dedicated training setups.
