[prestontony]

Looking for any info on parts that are fitted to my spesh max backbone frame. some of its not stock but looks decent.

Rear bottom swing arm not standard but cant find marks to identify
Chainguide looks like a world cup MRP but not the same? could do with id?

answering myself here thru research but think this is the SBC MAX Backbone Delerium frame w/aluminum swingarm ?
