Spoke Nipple Cn Spoke BN12, brass 14G (2.0 mm) x 12 mm, black, pack 144 pcs

Cn Spoke BN12 spoke nipples are brass 14G (approximately 2.0 mm) nipples with a length of 12 mm and a black finish. Supplied as a pack of 144 pieces, these nipples are designed for bicycle wheel building and spoke replacement. The brass construction offers inherent corrosion resistance and reliable mechanical strength, while the standard internal threading fits typical 14G spokes, allowing precise spoke tensioning during assembly and maintenance.

Advantages

Brass material gives good resistance to corrosion and provides durable thread engagement for long service life. The 14G (≈2.0 mm) diameter and 12 mm length make them compatible with many rims and spoke assemblies that require short nipples. The black finish ensures a discreet appearance on dark rims and hubs and helps reduce visible contrast. Supplied in a bulk pack of 144 pieces, the set supports multiple wheel builds or a complete spoke replacement project without frequent reordering.

Suitable for

• Building bicycle wheels that require 14G (2.0 mm) nipples of 12 mm length
• Replacing damaged or corroded nipples on existing wheels
• Small-wheel or low-profile rim builds where short nipple length is required
• Workshops and home mechanics performing multiple wheel services

Key specifications

• Material: brass
• Nominal diameter: 14G (approximately 2.0 mm)
• Length: 12 mm
• Finish: black
• Thread type: standard internal spoke thread for 14G spokes
• Pack quantity: 144 pieces

How to use

Select nipples that match the spoke diameter and rim requirements, then thread each nipple onto the spoke ends by hand until seated in the rim. Use a spoke wrench sized for 14G nipples to tighten and true the wheel, applying incremental adjustments to achieve even tension and correct lateral and radial runout. When replacing nipples, inspect spoke threads and rim bed for damage before installing new nipples; lubricating threads lightly can ease adjustment and reduce the risk of seizing.

Usage recommendations

For accurate wheel building, use a calibrated spoke tension meter and a suitable 14G spoke wrench. Avoid over-tightening to prevent spoke or rim damage. If rims have recessed or deep nipples holes, confirm 12 mm length provides sufficient thread engagement; choose longer nipples if necessary. Store unused nipples in a dry place to maintain finish and prevent contamination.
