Spectrum 98 Ti..
I built it myself so its a mix of a bunch of different shimano components I bought off ebay and craigslist.. I love it so far.. The crank is a pro team carbon (FSA)
The saddle is awesome and im so far beyond caring about the weight and size at this point.. The frame is made by merlin with merlin Ti for Tom at Spectrum. I believe its the same geometry as the extralight. The frame joints are simply beautiful, no beads or anything.. really nice..
