Fox Transfer SL Factory Dropper Seatpost (2023)

Starting at 327g for our 27.2mm factory series, the SL is 25% lighter than our standard transfer post, making it the lightest mainstream dropper on the market. With lever options for drop bars, flat bars, and 2x front shifters, it’s the perfect upgrade for Gravel riders and diehard xc racers who want the Performance of a dropper but not the extra heft.

Levers sold separately.

Features:

• NEW lightweight design.
• NEW Windows in lower post allow cable clamp/slack to be pulled from post side for compatibility with GRX-style dropper levers and minimises extra cable housing length.
• 2-position mechanical post that locks at the top and bottom only.
• Longer travel configurations offer exposed length of 290mm for taller riders.
• Shorter travel configurations offer shorter total length for smaller riders.
• Coil spring for consistent return performance.
• Internal routing only.
• 27.2, 30.9 and 31.6mm diameters.
• 50, 70, 75, and 100mm drop options.
• 70-85deg seat angles are supported.
• 7mm and 7×9 oval saddle rails supported.
• 1x lever is Matchmaker, Shimano GRX, and I-SPEC EV compatible.
• Available in Factory and Performance Elite Series. (Factory post includes Ti hardware for additional 10g weight savings)
