Rogue makes a add -on plate for Kettlebells and Dumbbells. The range is .05lb to 1.5 lb.
This solves issue of the in between weights. A discrepancy amongst kettlebell and dumbbells.
Even though you can get in between Dumbbells from certain companies. Example, They
make a 17.5lb hex dumbbell that fills the gap from 15-20lb. Several companies also
make a 22.5 hex dumbbell. I have included a few pictures of the fractional rubber
kettlebell, dumbbell plates. These sell out extremely fast.
