BCY 452Xtra® Bowstring Material

The BCY 452Xtra Bowstring material is widely regarded as the industry standard for premium custom bowstrings. Manufactured using 67% Dyneema® and 33% Vectran® in BCY’s patented construction, it delivers exceptional stability, durability, and consistency for serious archers.

Built on the proven performance of the original 452X, this enhanced version features improved abrasion-resistant Vectran®, helping reduce fraying while maintaining the same size and strength characteristics. As a result, archers benefit from longer service life and dependable performance.

Industry-Leading Stability

String stability is critical for maintaining accurate bow tuning and consistent shooting results. The Dyneema® and Vectran® blend provides virtually no creep, allowing the string to maintain its dimensions over extended periods of use.

Furthermore, consistent string length helps preserve brace height, cam timing, and overall bow performance.

Improved Abrasion Resistance

The upgraded Vectran® fibres offer greater resistance to wear and fraying. Consequently, bowstrings built with this material maintain a cleaner appearance and deliver long-lasting reliability.

In addition, the durable fibre blend performs exceptionally well under the demanding conditions of regular training and competition.

Trusted by Competitive Archers

Many professional string builders and competitive archers choose this material because of its proven track record. Therefore, it remains one of the most popular options for custom compound and recurve bowstrings worldwide.

Available in a wide range of colours, archers can also customise the appearance of their strings without sacrificing performance.
