Now this looks interesting... it seems canadian, but it has fastback rear stays, I had thought of a Rocky Summit but dropout and cable stops are different. For sure a great frame
It's for sale if you're interested! (I just can't tell you yet what it actually is).
With matching chro-mo threaded forks, stem and bars that were all resprayed together as a set. The forks, bar and stem are a slightly contrasting slightly darker purple colour than the main frame....
Am beginning to think that it's one of those unusual MTB frames that were built in incredibly small numbers by an Italian road frame manufacturer that never really got into the MTB marketplace? Could be anyway. There are "some" similarities to my Rossin Concept MTB, but not enough for me to suggest that that it what it is.
