Is this a good bike? Mavic

Just put it up on ebay. The wheels alone would cost about $2K new, however, it depends on the condition - the disc has that black spot, hard to tell from the photo what it is. If it's structural damage, then it's really not worth anything. The frame is a Yamaguchi track frame, I highly doubt that it is made of aluminium. Most likely steel. Cranks look like Mavic, post is pehaps Record Carbon? You need better quality pics. But yeah, you could probably get $1500 or so fo rthe whole shebang. Nice bike! Strange roommate....if it were me, I'd take up track cycling 😄 oh...you gotta figure out the size, which if you are a non-cyclist might be a bit tricky. measure from the center of the crankbolt to the center of the top tube on the frame to get a measurement...or to the top of the top tube for what we call a C-T measurement. Also the top tube length, from the center of each lug. Hope you know these terms? You won't be able to sell it without knowing the size. 😉
