My mountain bike is a GT Zaskar, so I call it 'NASCAR' or "NASCAR/ZASKAR" Yes, big NASCAR sticker on top tube!
My touring bike is a Mercian Vincitore, so I named it: "Vincitore"
My SRAM Force Compact GT Ti I call "SRAM."
My Ultegra Triple GT 853 (which is blue) I call "Blue 853."
My Ultegra Double crank GT Ti I call "Fast n' Light"
My MASI single speed I named "Faliero" even though its a CA built MASI, so maybe should be "Mario."
My Hercules 3-Speed is "Nigel"
My Calfee is too new, so no name yet. I could name it "Craig" after Craig Calfee, but that's too boring. It's a Tetra Pro, so maybe just "Tetra"

Best Regs,
