I picked these up from a guy that was going to scrap them. One is a ESPN X-Games Team Issue BMX bike. A GMB road bike with a S.R 555 derailleur? And after market parts I think wrote them down (SRAM Quarq RIKEN Crank, Huret stem shifter and on the hubs reads Mavic Ksyrium?) Explain to me road bikes please cause im dumber than a rock on both BMX and Road Bikes lol
