Excellent condition means there&#8217;s nothing to overcome here \u2014 just install and ride.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Workshop Wisdom:<\/strong> Always apply a light coat of grease to the insertion section of an alloy post in an alloy frame before installing. It prevents galvanic corrosion that can seize the post permanently in the seat tube. If using in a carbon frame, use carbon assembly paste instead \u2014 no grease.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Guarantee:<\/strong> You put in the miles, we put in the work! 30-day Guarantee, rest assured of fit, function and condition. \ud83d\ude42<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Keywords:<\/strong> Fuji seatpost, alloy seatpost, 31.6mm, 350mm, 25mm setback, single bolt, road bike seatpost, MTB seatpost, black, OEM takeoff<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Will this work? 31.6mm diameter \u2014 common oversized MTB\/road standard 350mm length, 25mm setback Single-bolt micro-adjust clamp \u2014 fore\/aft and tilt Standard 7x7mm rail clamp 360g \u2014 alloy, road\/MTB universal Fits any frame with a 31.6mm seat tube ID Condition: Excellent.
