Narrow Wide 110 BCD // 5-Bolt Chainring

Convert your vintage 26" MTB to a clean 1x setup without modifying your frame. Bolts straight onto any 110 BCD 5-bolt crankset, the same pattern used on most vintage mountain bikes. For optimal chainline, you may need to adjust your bottom bracket spindle length.

• Sizes: 36T / 38T / 40T. Pick based on terrain and gearing range.
• Narrow-wide tooth profile: alternating tooth width holds the chain under vibration and rough terrain, so you can drop the front derailleur entirely.
• Material: CNC-machined, anodized aluminum alloy. Light, corrosion-resistant, built to outlast the bike.
• Chain compatibility: 1-12-Speed

Note on colorway: "Titanium" refers to the finish, not the material. The ring is aluminum alloy throughout.
