EVOSID Road Chainring 40-50T Crown Folding Narrow Wide Sprocket

EVOSID Road Chainring Narrow Wide Tooth Profile and Crown Folding Technology

The narrow wide tooth profile alternates tooth widths to mechanically grip your chain, reducing chain drop incidents that cost time and momentum during competition or challenging rides. Crown folding mechanism allows the EVOSID Road Chainring to collapse into itself, letting you pack the bike into a suitcase or mounting frame without removing the drivetrain entirely. This narrow wide design works across eight through twelve-speed cassettes because tooth spacing remains consistent with modern Shimano and SRAM systems regardless of speed count. Available in 40T, 42T, 44T, 46T, 48T, and 50T options, you select exactly the ratio your gearing strategy demands whether climbing alpine passes or maintaining high-speed cruises. Lightweight aluminum and hardcoat anodize finish ensure the sprocket wheel survives seasons of salt spray, mud contact, and UV weathering without visible corrosion or performance loss.
