The stems fit Grand Bois handlebars and many others (25.4 mm clamp). They fit on most non-French bikes (22.2 mm steerer). Note: Nitto NP stems are about 3-4% longer than their nominal size. For example, the 9 cm actually measures 9.3 cm, and the 12 cm measures 12.5 cm. An optional decaleur (shown in the photos on the right and left) allows you to mount your handlebar bag securely, yet make it easy to take the bag with you when you park your bike.
Nitto NP Stem
Once upon a time, most stems were made from forged aluminum. Cinelli, 3TTT and others made them. They were pretty, relatively lightweight, and stem failures were unheard of. Fortunately, Nitto still makes a forged aluminum stem. It used to be called “Pearl”, but now it’s just the NP. It’s the same stem, with the same top-quality finish. Made in the Japan. 5 year warranty.
