FBV to FIREUpdated a year ago
Our FIRE Rings are available in four different radiuses - 3/8", 1/2", 5/8" and 3/4". This video helps to illustrate how Sparx has optimized the FBV profile to provide more glide while maintaining the bite. Below, you'll also find a conversion chart for converting traditional FBV measurements to correlate with FIRE rings.
FBV to FIRE Conversion chart:
- 90/50 = 3/4" ROH (more glide)
- 90/75 = 5/8" ROH
- 100/50 = 1/2" ROH
- 100/75 = 3/8" ROH (more grip)
