Ritchey Comp Seatpost

A zero-offset seatpost positions the saddle directly over the seat tube rather than setting it back. This promotes a more aggressive, forward-leaning posture that is often preferred by riders looking to optimize power transfer and aerodynamics.

This model has a specific diameter of 30.9 mm. You must verify your bike frame's seat tube diameter before purchasing, as this is not a universal size and cannot be adapted with shims safely.

Yes, the carbon fiber material is naturally more compliant than aluminum. It helps dampen high-frequency road vibrations, which can reduce fatigue and improve comfort on longer rides.

The 400 mm length refers to the total length of the post. While you can cut the post to reduce weight if you don't need the full length, ensure you maintain the minimum insertion depth required by your frame manufacturer to prevent structural failure.

The UD (unidirectional) matte finish is durable and resists scuffs better than high-gloss options. It provides a clean, understated look that hides minor wear well, though it should be cleaned with a soft cloth to maintain its appearance.
