The BB4 is designed to improve driving distance. It's alpha-beta forged face increases ball speed of the face there by increasing distance. The bellowed sole also works to increase the ball speed. This is a key design feature.

Upon impact club the bellowed sole helps the face compress and decompresses to launch the ball forward. The decompression is from front to back instead of all over. This release creates a stronger ballistic trajectory for more carry, run, and less spin.

The BB4 also has a center of gravity is slightly higher than most drivers. It aligns with the compression of the bellowed sole. As such, golfers get increase forgiveness on misses. The bellowed sole makes this driver an ease to play with.

The BB4 is a 2 pieces head made of high-end materials like a forged 6-2222 S α β Ti face and 8-111 Ti precision cast face. The standard weight installed is 6g but you can also purchase 3g/8g/10g/12g. The BB4 is 455 cc’s and comes standard at 197g
