About This Product
The Box Two Center Clamp Stem-1 1/8" is a brilliantly designed cold forged aluminum stem. Box has moved the rear pinch bolts to the front of the stem to eliminate potential knee versus stem bolt conflicts. With a 22.2mm bar bore, these stems require at least 45mm of exposed steerer tube to securely clamp on. Just one note: They are not compatible with carbon fiber steerer tubes.
