1975 Vintage 61cm Masi Gran Criterium Reynolds 531 Steel Road Bike. The Masi Gran Criterium of the 1970s is a racing machine that is highly sought after among vintage bicycle enthusiasts. Frame is a Used Original Paint US Version Gran Criterium, Shows wear & use, has some scratches, touch up, finish & deals loss, possible small dents but I didn’t see any. The bike is official 61cm and measures 59cm from the center of the bottom bracket to the center of the top tube or 60.5cm Center to Top of the top tube. The top tube is 57.5cm center to center and the head tube is 172mm tall. Specs say frame Frame and Fork are Reynolds 531 Steel Tubing but there are no decals. The Parts are Nicer than the Frame set, I suspect somebody rebuilt this with the best parts they could find, they look like real good used and some NOS parts, period correct but not exact dating. The bike has Campagnolo Record Parts: Nuovo Record Front and Rear Dérailleurs, Shifters, Bottom Bracket, Brakes & Levers. Headset & Cranks are Super Record. It has a Leather Brooks Saddle, and Cinelli Stem and Handlebars. The 27″ x 1 1/4″ wheels have Campagnolo Record High Flange Hubs laced to Super Champion Competition Gentleman Rims, The Rims show age & wear. The Serial # MC 61 07 XX is on the bottom bracket and and from the research I did that’s 1975 and the MC 61 stands for 61cm. Cool Old Retro Rider. Interested in other Bikes?
