Starting at 375g for the 27.2mm Factory Series, the SL is 25% lighter than the standard Transfer post, making it the lightest mainstream dropper on the market.  With lever options for drop bars, flat bars, and 3x 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.

• 70-85 degree seat angles are supported
• 7mm and 7x9 'Ob-round' saddle rails are supported
• 1x lever is Matchmaker, Shimano GRX, and I-SPEC EV compatible
