This Cervelo Super Prodigy serial # OR has a 59 cm top tube and seat tube measured center to center, head tube is 181 mm long. It has Ritchey drop-outs, 130 mm spacing, uses a 1 inch fork and a 27.2mm seat post. It's in very good condition, no dents but there are a few paint chips. From the look of the drop-outs it appears to have seen very little use. Here's what Cervelo had to say about it “A steel bike that performs like no other. New lightweight Ultra Foco custom-designed Thermacrom tubeset steel frame design optimized for stiffness-to-weight. Complete Nickel-plated frame for corrosion & abrasion resistance. Exposed Nickel chainstays & seatstays."
