Serotta Coeur d’Acier Frame | 54cm Medium | Columbus C4S Steel | Deep Burgundy

Description

⭐Condition
Near mint — excellent paint throughout with three minor cosmetic flaws: cable rub on the head tube (hand-painted touch-up, covered by cables), minor chain rub on the chainstay, and a small chip on the down tube. All logos are perfect and the finish maintains that distinctive Serotta depth. No structural issues.

🚴The Ride
Columbus C4S steel delivers that connected, communicative feel serious riders seek — responsive under power, smooth over distance. The carbon wishbone seatstays absorb the high-frequency chatter that wears you down on long rides without softening the frame’s handling character. Compact geometry keeps the front end low and the rider engaged. This is a frame that rewards effort and pays back in feel.

🔧Workshop Wisdom
The single-piece machined chainstay and dropout is worth a closer look — stronger than welded alternatives and adds its own road damping. The carbon seatstay is molded as one piece, curved to work, with steel caps bolted at the dropouts. Serotta’s craftsmanship lives in details like these.
