Cut serious weight from your Colnago Y1RS with a handmade carbon seatpost weighing as little as 92 grams.
The Tonale carbon seatpost is designed specifically for the Colnago Y1RS. It gives riders a genuinely lightweight alternative to the original seatpost while maintaining the precise fit required by Colnago’s aero frame.
Each seatpost is handmade in Italy from premium carbon fibre using high-pressure moulding and an internal silicone bladder. This process creates a clean, consistent carbon finish inside and out.
