Thank you Lou
The Guys are doing a very good job, i'm becoming to be proud of all this pieces,
the original cush drive was very similar but rough and too small for our need so we did a new one,
At the beginning i planned to use Carlo's floating brake caliper holder, i get it from Carlo on my latest visit to him.
but i want to use the 240 mm floating disc you see in the picture that is smaller to fit with Carlo's holder made for 260 mm rotor ( of course i will keep this for next projects

). So we machined a new holder for the caliper, even the rear sprocket is custom made starting from a semi-finished sprocket.
About the floating disc it came together with a Epm wheel. Cast iron (Ghisa) rotor and aluminum hub.
