This 53cm frame is an exceptional fit recommended for riders between 5'9\" and 6'1\". Showcasing its distinctive factory Gunmetal Grey paint with a contrasting Radiant Red head tube and matching housing lines, this classic machine was brazed in Waterloo, Wisconsin, utilizing a world-renowned Reynolds 531 steel tubeset—treasured by collectors for its natural compliance and springy power delivery.\u003c\/p\u003e\n\u003cp\u003eThe technical setup is beautifully configured for both historic group rides and daily loaded commutes. The drivetrain features a full vintage 3x6 Shimano 600 mechanical groupset, shifting across an era-correct 50\/44\/28T Shimano Biopace triple crankset. These non-round chainrings are specifically engineered to smooth out dead spots in the pedal stroke during steep, high-torque climbs. Traditional down-tube levers dictate the gear steps with tactile mechanical precision, working in perfect unison with premium Shimano 600 side-pull calipers for reliable, linear brake modulation.\u003c\/p\u003e\n\u003cp\u003eThe build character leans into traditional aesthetic details, rolling on durable Matrix Titan alloy rims laced to smooth Shimano 600 hubs. These are wrapped in high-volume 700x28c Michelin Dynamic Classic tan-wall tires, yielding an exceptionally plush, vibration-killing footprint on rough city chip-seal roads. The cockpit features a classic Sakae Custom Road Champion handlebar measuring 400mm across, paired to a compact 70mm SR Custom aluminum stem for tailored handling ergonomics. Completed with matching red cloth bar tape and a period-correct Selle San Marco Laser suede saddle, this Trek 520 Cirrus arrives fully dialed, expertly serviced, and 100% road-ready.\u003c\/p\u003e\n\u003ch3\u003e\u003cbr\u003e\u003c\/h3\u003e","brand":"Trek","offers":[{"title":"Used","offer_id":45407278825519,"sku":"1290","price":1500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0599\/6272\/0303\/files\/trek_vintage_gray-1.jpg?v=1780343916","url":"https:\/\/lebelbicycles.com\/products\/trek-520-cirrus-53cm-1987","provider":"Lebel Bicycles","version":"1.0","type":"link"}
