I recently bought this mountain bike frame, It seems to be high quality tig welded alloy. I initially thought it was a Specialized frame because it was so lightweight and quality welds. But now I have my doubts. Any help to identify it would be greatly appreciated. The frame is 21inch from centre of crank to top of seat post. And has 2 clusters of 3 cable runs on top of the top tube which I thought was unusual as most are underneath. I have no idea of the original forks or crank/running gear or brakes or wheels, it now has sr suntour lockout forks and hydraulic discs front and rear. It originally ran v brakes I think. If there's anything relevant I can look at to help identify it please advise me.
