Elevn Carbon Pivotal Seat Post Aero 25.4mm

Product Overview

The Elevn Carbon Pivotal Seat Post is a lightweight aero-profile seat post designed specifically for Chase RSP frames. Built as a carbon monocoque structure, it weighs just 58 grams and accepts pivotal saddles via a single-bolt mounting system. The aero 25.4mm shape matches Chase RSP 3.0, 4.0, and 5.0 frame seat tube profiles.

Key Features

• Carbon monocoque construction - Single-piece carbon layup eliminates joints and bonding points for consistent strength throughout the post length

• Aero profile - Non-round cross-section reduces aerodynamic drag and matches specific Chase RSP frame seat tube shaping

• Pivotal saddle compatibility - Single-bolt mounting system accepts standard pivotal saddles for secure attachment and precise angle adjustment

• Ultralight weight - At 58 grams, this post significantly reduces overall bike weight compared to aluminum alternatives
