Where did you find this? The via had no link and googling didn't seem to help any. Even doing an image search turned up nothing. I've seen one other picture of this bike and I want to see if there's any more info on the build. Been wanting to try building something similar, only with an actual Triumph frame and not BSA like this. I can see how using that frame probably made it easier though making the mono shock conversion and modern front end.
I had actually gotten it from another repost but did some detective work and came up with this link:http://rocket-garage.blogspot.de/2013/01/the-tronsa-aka-pearl-necklace.html
