Extreme DurabilityStainless Steel 316 CNC Machined Internal Steering Stop Lugs
Product Overview:
Our CNC-machined internal steering stop lugs are engineered to prevent over-rotation damage in high-stress cycling and motorcycle applications. Manufactured from marine-grade stainless steel 316, these components provide corrosion resistance, extreme durability, and precise steering control.Perfectly integrated into bicycle headsets or motorcycle triple clamps, these lugs are 5-axis CNC contoured to ensure 45° precision contact surfaces, delivering smooth steering while protecting your frame and fork from impact damage.
Key Features & Benefits
| Feature | Specification | Advantage |
|---|---|---|
| Material | 316 Stainless Steel (ASTM A276) | Saltwater/sweat resistant, ideal for coastal/MTB use |
| CNC Process | 5-axis milling + EDM finishing | Complex 3D contours with ±0.01mm accuracy |
| Contact Angle | 45° precision machined | Optimized steering lock without sudden jamming |
| Load Capacity | 200Nm torque resistance | Withstands aggressive riding and off-road impacts |
| Surface Finish | Electropolished (Ra 0.2μm) | Reduces friction, prevents galling |
| Weight | 15g (typical road bike lug) | Minimal impact on overall bike weight |
| Compatibility | Fits 1-1/8" to 1.5" tapered headtubes | Universal for road, MTB, and motorcycle applications |
| Certifications | ISO 9001, EN 14766 (MTB standard) | Quality assured for competitive use |
Applications:
Mountain Bikes – Enduro/DH bikes with aggressive steering angles
Road Bikes – Prevents damage in crit racing/tight corners
E-Bikes – Protects heavy motors from over-rotation stress
Motorcycles – Track-day bikes with limited steering range
Our Advantage:
Precision CNC Machining – Ensures consistent quality and perfect fitment.
Internal Steering Stop Lugs – Prevents excessive wheel rotation, protecting CV joints and tie
rods.
High-Strength Material – Corrosion-resistant and load-bearing for demanding conditions.
OEM/Aftermarket Compatibility – Designed to meet or exceed original specifications.
Customization Available – Material, finish, and dimensions tailored to your requirements.
Technical Comparison vsTraditional Stops
| Parameter | Our CNC-Machined Lugs | Cast/Punched Stops | Advantage |
