I give a triple thumbs up to floating sprocket hubs. I was busting chains right and left until I switched to one. Haven’t suffered a broken chain in 2 years. A floating hub with o-ring chain is the way to go. The carrier itself is just as reliable as a fixed one.
I’ve had experience with it a few times its defiantly worth speed if your looking for that last bit and speed down the straight but on a leopard a floating sprocket is pretty radical and if you even ding a curb so bye bye to your chain.
