Durga and JC Concepts Rulux Wheels

[MR_C]

Helloooo

Just wanted to pick a few brains if possible. I am looking to replace the standard Durga / 501 wheels with JC Concepts Rulux wheels. I have seem photos of them on both a Durga and a 501 and they look awesome; however when i have looked into buying them there are two model types listed - B4 and B44.

Just wanted to ask which ones fit the Durga / 501 and if they use the same size fitting as the standard wheels or if they are 12mm size?

Also, Where is best to buy?

And one more thing! When tyres have a compound colour (green for example) would these be a hard compound or soft?

Cheers
