Darimo Carbon Seatpost for Colnago Y1RS (+7.5mm / −7.5mm Offset)
One of the few remaining meaningful weight savings on the Y1RS. This is a purpose-built seatpost for riders who want to reduce mass at saddle height and select the correct setback for their fit.
What this upgrade does
The Colnago Y1RS is already highly optimised. There are very few areas left where you can remove weight without compromise.
This seatpost targets one of them — reducing mass high on the bike while maintaining correct saddle position.
Key points
- ⚡Reduced mass at saddle height
- 🔧Available in +7.5mm or −7.5mm offset
- 🧱Designed for seated rider loads
- 🎯Y1RS-specific seatpost interface
Choosing the correct offset
+7.5mm offset moves the saddle slightly forward relative to the bottom bracket.
−7.5mm offset moves the saddle slightly rearward.
Match your current bike fit where possible. If unsure, measure your existing saddle setback or get in touch before ordering.
Why saddle position matters
Setback affects how your hips sit over the pedals. Small changes here influence comfort, power delivery, and how the bike feels when riding seated.
This is a fit decision first, not a feature to experiment with after purchase.
Important notes
Do not cut this seatpost. Darimo posts are engineered for strength and weight as supplied. Cutting can compromise structural integrity.
Use correct torque. Follow the torque specification for the Y1RS seatpost clamp hardware. Under-clamping can slip; over-torquing risks damage.
FAQs
What’s the difference between +7.5mm and −7.5mm?
+7.5mm positions the saddle slightly forward. −7.5mm positions it slightly rearward.
This changes your effective riding position relative to the pedals, not the bike’s geometry.
How do I know which offset I need?
If your current fit is working, match your existing saddle setback. If you’re unsure, measure from the saddle tip to the bottom bracket or get in touch and we’ll help you choose correctly.
Can I change the offset after installation?
No — offset is determined by the seatpost you select. Choose the correct option before ordering.
Can I cut the seatpost?
No. Cutting is not recommended and may compromise the structural integrity of the post.
What torque should I use?
Follow the torque specification provided for the Y1RS seatpost clamp hardware. If unsure, refer to Colnago documentation or your mechanic.
Is this a generic Colnago seatpost?
No — this is designed specifically for the Colnago Y1RS seatpost interface.
