A new challenger appears...
This is cool... there's finally an adjustable hardstyle kettlebell on the market. While I prefer the competition style kettlebell design, this could be perfect for someone who prefers the old school, hardstyle kettlebell as it solves the problem of handle sizes changing as you move up in weight. The handle geometry also seems to be on par with the typical competition style kettlebells. I'm not in the market, but there might be a few who are interested. https://www.eryxfitness.com/en/product/adjustable-kettlebell/
