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.
Choose Your Length
The Tonale Y1RS seatpost is available in 240mm, 270mm and 300mm lengths. Each size may be shortened by up to 30mm from its original length.
Reference weights supplied by Tonale. Actual weight may vary by approximately 4%.
Two Offset Options
Two saddle-position options are available:
- 0mm option: +7.5mm actual offset
- -15mm option: -7.5mm actual offset
Select the option that matches your required Y1RS saddle position and bike fit.

Custom lengths are available for taller riders, with a reinforced carbon layup where required. Contact Bspoke Velo with your required length and rider weight before ordering.
