Carbon Fiber Aero Seatpost | 27.2 x 285mm | 25mm Setback | TT-Tri- Road

Description

Will this work?

• 27.2mm diameter — fits standard high-end road and steel frame seat tubes
• 285mm total length, 140mm adjustable range, 25mm setback
• Single-bolt saddle clamp —easy  adjustable fore/aft and tilt
• Standard 7x7mm rail clamp
• 208g — ultralight aero profile

Condition: VG above the insertion line — carbon weave sheen intact, clamp hardware functional. Below insertion: surface scuffs from clamping. A deeper scratch in the upper laminate layer is visible on the shaft — does not penetrate through to structural layers

Notes from MyBikeThing: At 208g this is a genuinely light aero post — The aero profile reduces drag over a round post on longer road rides.

Workshop Wisdom: Never use grease on carbon seatposts in carbon frames — use carbon assembly paste instead. In alloy frames, a light smear of grease is fine. Torque the clamp bolt to spec (typically 5–8Nm) — overtightening carbon posts is the most common cause of laminate damage. Always use a torque wrench.

Guarantee: You put in the miles, we put in the work! 30-day Guarantee, rest assured of fit, function and condition. 🙂
