Hoyt Handle Formula Faktor 2017 Since 1931, Hoyt recurve risers have been the innovating force in the recurve market—continually advancing industry standards of engineering and performance. We are proud to continue that tradition in 2017 by introducing the most high-performance, stable recurve riser we have ever produced: the all-new Formula Faktor. The first thing you will notice about the Faktor is the significantly wider front aspect of the riser. This increased width greatly enhances stability and aiming, and reduces the side-to-side movement normally felt in the riser at release, while delivering a very responsive shooting experience. Though wider, the Formula Faktor is specifically engineered with optimized flex patterns to ensure ultimate accuracy and forgiveness. In addition to this groundbreaking riser design, based on the Earl Hoyt geometry, the Faktor 25” and 27” models both bring a slew of advanced features and key technologies to the table.
