Fox Transfer SL Factory 2023 Dropper Seatpost

Super Light Done Right

At up to 167 grams (~25%!) lighter than the regular Transfer post, it’s the lightest mainstream dropper post on the market. Period. With options from 27.2mm x 50mm all the way up to 31.6mm x 150mm and lever options for flat bars, drop bars, and 1x and 2x drivetrains Transfer SL brings the word “shred” into the superlightweight Trail, XC and Gravel conversation.

“Factory” says it all. The best-of-the-best technology we have to offer is available in our Factory Series models with our buttery smooth, ultra durable Genuine Kashima Coat. These products are World Cup proven.
