Excalibur Hybrid X Crossbow String

Excalibur Hybrid X Crossbow String – High-Velocity BCY Mercury 2 Fibre

The Power of BCY Mercury 2 Technology

This is no ordinary string. BCY Mercury 2 uses a high-strand count of ultra-fine fibres, allowing for a thinner string diameter without sacrificing immense strength. For you, this means reduced aerodynamic drag and less friction on the rail, directly translating into the superior performance of your Excalibur Hybrid X. The centre serving is applied under extreme tension to ensure it locks onto the string and provides maximum resistance against the wear and tear of the trigger claws and bolt nocks.

Usage and Setup Guide

Before installing your new string, inspect your crossbow's limbs and cams for any wear. Always use a crossbow stringer aid for installation to ensure a safe change and to protect the limb tips. Once installed, check your brace height (the gap between the string and the string stops). If the string is too close to the stops, you can add a few twists (following the direction of the factory twist) to achieve the perfect setup.

Care Instructions for Longevity

To ensure your Excalibur string lasts for hundreds of shots, follow these maintenance tips:

• Regular Waxing: Apply crossbow string wax to the exposed fibre sections every 20–30 shots. Rub it in with your fingers until the friction heat melts the wax into the strands.
• Serving Inspection: Always check the centre serving before shooting. If you see signs of separation or fraying, it’s time for a replacement or reserve.
• Rail Lubrication: A well-lubricated rail reduces the heat generated by friction, significantly extending the life of your serving.

What to Avoid?

Never "dry fire" your crossbow! Firing without a bolt is the fastest way to snap the string and damage the limbs. Also, keep the string away from sharp objects and harsh chemicals. Store your crossbow in a cool, dry place to prevent the fibres from degrading over time.

Recommended Accessories

For the best maintenance and shooting experience, consider adding these items:

• High-Quality String Wax – for essential fibre hydration.
• Rail Lubricant (Rail Lube) – for smoother shots and serving protection.
• Stringing Aid (Stringer) – for safe and easy string maintenance.
• Hybrid X Cable Set – it’s best practice to replace strings and cables together for perfect synchronization.

Did you know? Mercury 2 material was originally developed to tackle the vibration issues in ultra-fast crossbows. By using this string, your Excalibur won't just be faster; it will also feel smoother and potentially quieter during the shot sequence.
