28T SRAM X01 Chainring – 94mm BCD North Shore Billet MTB Upgrade

NSB Variable Tooth Chainrings – Precision Chain Retention for Single-Ring Riders

Engineered for mountain bikers and gravel riders who demand reliability, the NSB Variable Tooth Chainrings feature an innovative “Thin-Thick” tooth profile that keeps your chain securely in place—even on rough trails and aggressive climbs. Unlike traditional chainrings, this design alternates between thicker and thinner teeth to minimize lateral movement, virtually eliminating chain drops when running a 1x drivetrain.

Key Features & Benefits

• Optimized Chain Retention – The variable tooth thickness reduces slack, ensuring smooth shifts and fewer drops.
• Premium 7075-T6 Aluminum – CNC-machined for strength and durability while keeping weight low.
• Sleek Black Anodized Finish – Resists wear and corrosion, with laser-etched graphics for a clean look.
• Compatibility – Fits 10/11-speed drivetrains (94mm BCD), ideal for modern 1x setups.

Why Choose NSB Over Standard Chainrings?

Perfect for enduro, trail, and bikepacking, this 28-tooth chainring delivers confidence when you need it most—no front derailleur required. Upgrade your ride with precision-engineered performance.
