Darimo Carbon Seatpost for Colnago V5RS
Crazy fact: Darimo aero seatposts weigh as little as ~95g, and on a V5RS build, swapping the seatpost can save more weight than upgrading the saddle — without touching your fit or contact points.
This is where serious V5RS builds go next
The Colnago V5RS is already ruthless: stiff where it counts, light without gimmicks, and built for WorldTour abuse. At this level, most “easy upgrades” are gone.
The Darimo V5RS-specific seatpost is for riders who keep going anyway — cutting meaningful weight from the highest point on the bike and refining ride feel without changing your position.
- ⚖️ Meaningful weight savings from the highest point on the bike
- 🧱 Precisely controlled carbon layup — no excess wall thickness
- 🧠 V5RS-specific profile, not a reworked generic post
- 🏁 One of the final upgrades on an already optimised V5RS build
Why weight weenies care about the seatpost
Grams removed up high change the whole feel of the bike more than the same grams removed down low — especially when you’re out of the saddle and loading the frame through accelerations.
Compared to the stock Colnago post, the Darimo typically removes 70–120g from the highest point on the bike, depending on size and layup — weight you feel every time you stand up and accelerate.
Darimo’s approach is simple: remove material everywhere it isn’t structurally required, keep strength where it is, and tune the layup to ride properly on real roads.
Compatibility
Designed specifically for the Colnago V5RS seatpost interface. This is not a universal post and not a “close enough” aero shape. Fit is exact and intended to be installed once and left alone.
FAQs
Is this seatpost V5RS-specific?
Yes. This post is engineered specifically for the Colnago V5RS seatpost profile and clamping interface. It is not intended to fit other Colnago models or generic aero posts.
Can the seatpost be cut?
No. Darimo seatposts are engineered with controlled fibre orientation and wall thickness. Cutting can compromise structural integrity and is not recommended.
Will it change the ride feel?
Yes — in a good way. Reduced mass up high and a tuned layup typically gives a calmer feel over rough tarmac without making the bike feel soft under power.
Is it suitable for heavier riders?
Darimo specify rider limits per model. If you’re near the upper end, install correctly, avoid repeated height changes, and don’t treat it like a workshop beater part — it’s a performance component.
Is this worth it over the stock Colnago post?
If your V5RS build is already dialled (light wheels, premium finishing kit, quality tyres), this is one of the few remaining places to remove meaningful weight and improve feel. If the rest of the bike is still stock, start with bigger wins first.
