At up to 167 grams (roughly 25%) lighter than the Transfer post, the Transfer SL is the lightest mainstream dropper post on the market. The two-position design means the dropper can be ridden as either fully extended or fully retracted with size/travel options from 27.2mm x 50mm up to 31.6mm x 150mm. With lever options for both flat bars and drop bars, the Transfer SL brings simplicity and lightweight performance to Trail, XC and Gravel disciplines. *The Transfer SL Seatpost does not include a dropper lever.
