Found this frame a few years back,nice aluminum,nasty welds but attractive. It became available cheap so I scooped it up. And then a vintage time trial wheel popped up on CL but around the block,and fit the frame nicely. I was able to use a lot of my last spares in build but Scotty’s in Willimantic helped with missing pieces. Derailer and musclebike handlebar shifter mated nicely without adjustment. Brakes are weak but that will be corrected when rear wheel gets replaced with more ordinary and functional setup. I was told the frame is Del Sol but I could not find anything online. Could become a favorite/ keeper. Enjoy...Stevil
