Sorry guys it was late. Its a new XXL conversion with TDR conversion and the Castle/neu 1520. It was not a difficult conversion its just I work a lot of hours and I really took my time.
I have yet to really run it yet as I have some more plans for it. I can say that just running it around my living room tile I was happier then a 4yr old on christmas morning. I love its size with the huge tires.
