Darimo Carbon Seatpost for Colnago C64 / C68 / V-Series
Colnago frames like the C64, C68 and V-Series are built to feel fast and precise. If you’re upgrading one, the seatpost is one of the cleanest places to remove weight and improve ride feel without changing what makes the bike special.
Refine the build — without changing the character
This Darimo carbon seatpost is made specifically for Colnago’s D-shaped platform used across the C64 / C68 and V-Series family. The result: meaningful weight reduction up high, a calmer feel on rough roads, and a cleaner, more purposeful finish than stock.

FAQs
Which Colnago models does this fit?
This Darimo seatpost is built for Colnago’s D-shaped platform used across C64, C68, V3RS, V4RS, V3G3 and X frames. If you’re unsure on your exact frame year or seatpost platform, check before ordering.
Do I need a new wedge / clamp, or does it come with one?
Darimo supplies the seatpost only. Your Colnago frame uses an internal clamp/wedge system — this post is engineered to work with the original Colnago clamp/wedge hardware supplied with your frame. Retain and reinstall the factory hardware during installation.
What torque should I use on the seatpost clamp?
Always follow Colnago’s specification for your exact model and year. Many setups are commonly around 5 Nm, but confirm your manual. Use a calibrated torque key and carbon assembly paste.
Can I cut the seatpost to fine-tune saddle height?
No. Darimo seatposts are engineered to be used at full length. Cutting the post is not recommended and may compromise strength. Choose the correct length for your setup.
Does it support Shimano Di2 / internal wiring?
Yes. These Colnago frames support internal electronic routing, and on Shimano Di2 builds the battery is commonly housed internally within the seatpost or seat tube depending on configuration. If your build requires internal routing, confirm your frame’s configuration before purchase.
How much weight will I actually save?
It depends on the OEM post, but 100–200g savings are common. On a Colnago build, that’s meaningful — especially when saved high on the bike.
Will it change the ride feel?
Most riders notice a calmer feel over rough surfaces thanks to carbon’s damping characteristics, without turning the bike soft or vague. It’s refinement, not a personality change.
