Description
BCY X-99® Bowstring Material
The BCY X-99 Bowstring material is engineered for archers who demand exceptional stability, durability, and consistency. Constructed from 80% SK99 Dyneema® and 20% Vectran®, it delivers excellent performance for both compound and recurve bows while maintaining minimal stretch over time.
Designed with BCY’s patented construction process, this premium string material offers dependable shooting characteristics and long-term reliability. As a result, it has become a popular choice for competitive archers and professional string builders.
Exceptional Stability and No Creep
One of the key advantages of this material is its excellent dimensional stability. The blend of SK99 Dyneema® and Vectran® helps minimise creep, allowing the bowstring to maintain its length and performance over extended use.
Furthermore, stable string dimensions help maintain consistent brace height, cam timing, and overall bow tuning.
Durable and Abrasion Resistant
A quality bowstring material must withstand repeated shooting cycles. Therefore, BCY X-99 is designed with high abrasion resistance to support long service life.
In addition, the material produces low fuzziness during use, helping maintain a clean appearance and reliable performance.
Suitable for Compound and Recurve Bows
Although many archers use X-99 for compound bows, it also performs exceptionally well on recurve setups. Consequently, it provides versatility for archers who want premium string material across multiple disciplines.
For best results, BCY recommends keeping string-building tension below 150 pounds during construction.
