Onyx Endcap, Knurled – Left, 20mm Thru – Stainless Steel

Product Overview The Onyx Endcap is a precision stainless steel left-side endcap designed for 20mm thru-axle hubs. The knurled finish provides secure grip during installation and removal without tool marks or slipping. Manufactured as a custom component, each endcap is made to order for exact fit and finish specifications on Onyx hub builds.

Key Features

• Stainless Steel Construction – Corrosion-resistant material maintains finish and strength through extended use and exposure to moisture; resists rust and oxidation
• Knurled Finish – Textured surface provides secure grip during installation and removal; prevents slipping during hand-tightening without requiring excessive force
• Left-Side Positioning – Specifically designed for left (non-drive) side hub positioning; precise threading ensures consistent fit with Onyx hub body
• 20mm Thru-Axle Compatible – Engineered for 20mm thru-axle standard; ensures secure axle retention and maximum wheel stability under high-load racing conditions
• Precision Threading – Custom-manufactured to exact specifications for flawless integration with Onyx hub body; eliminates cross-threading or loose fitment
• Custom Made-to-Order – Each endcap manufactured individually to match your specific Onyx hub build and customization choices

Technical Specifications

• Position: Left (non-drive) side
• Thru-Axle Size: 20mm
• Material: Stainless steel
• Finish: Knurled
• Compatibility: Onyx custom hubs with 20mm thru-axle specification
• Manufacturing: Custom made-to-order
• Production Timeline: 3–4 weeks standard; up to 4 weeks in some cases due to custom build backlog

Compatibility and Ideal Use Cases

• Fits: Onyx custom-built hubs with 20mm thru-axle specification; left-side position only
• Best For: Onyx hub builds requiring left-side thru-axle endcap replacement or custom hub assembly; modern BMX forks with 20mm thru-axle dropouts
• Ideal Riders: Those building custom Onyx hubs with specific design and color preferences; riders using 20mm thru-axle forks (Box Hex Lab, Ikon Pro, etc.)
• Installation: Hand-tighten using knurled grip; do not over-tighten—snug fit is sufficient for secure axle retention
• Not Recommended For: Non-Onyx hubs; 10mm, 15mm, or other thru-axle sizes; right-side positioning

Important Notes – Custom Order Requirements

• Made-to-Order and Final Sale – All Onyx products are custom-manufactured and final sale; non-returnable regardless of circumstances
• Production Delays – Current lead time is 3–4 weeks from order to completion due to custom build backlog; some orders may take up to 4 weeks
• US Shipping – Orders placed in the USA ship directly from Onyx upon completion
• International Shipping – Orders shipping outside the USA route through BRG in California before final delivery
• Verification Required – Double-check all specifications, finishes, and positioning before confirming order; changes after manufacturing begins are not permitted

Maintenance Note Stainless steel endcap requires no special maintenance. Periodically check knurled grip for any buildup; clean with dry cloth if needed. Do not apply grease to threading areas—dry fit only.
