Darimo Carbon Seatpost for Specialized S-Works Tarmac SL6
Context: The SL6 is one of the last Tarmac frames where reducing mass up high still makes real sense. If you’re building a true weight-focused SL6, the seatpost is not cosmetic — it’s functional.
Why Darimo on an SL6?
The stock SL6 seatpost is solid, but not light. Darimo replaces it with a frame-specific carbon post designed to minimise weight while maintaining ride feel and structural safety.
This is aimed squarely at experienced riders who already understand fit and are optimising the finishing kit.
What you get
- Significant weight reduction over OEM post
- Carbon layup tuned to rider weight
- Clean, understated finish — no visual noise
- Designed specifically for the SL6 seat tube profile
Fit notes
This seatpost is compatible with the Specialized S-Works Tarmac SL6 only. It is not interchangeable with SL7 or SL8 posts.
Do not cut: Darimo seatposts are supplied at the correct length and should not be shortened.
Yes — especially compared to newer frames where the seatpost is already optimised. The SL6 still offers genuine gains here.
Options depend on your fit. If you’re unsure, confirm your current saddle setback before ordering.
Typically 4–6 weeks. Each post is built to order.
Internal routing is supported where required, but this is not a deciding factor for most SL6 builds.
