Dropper posts have revolutionized the way mountain bikers ride their bikes. Back in the day, riders had to dismount their bikes before a descent to lower their seatposts so they could get a lower center of gravity and then dismount again when they got to a steep hill. With a dropper post, long gone are the days of dismounting. Riders can just flick a lever and lift and lower their seat with little to no lag time in between. SDG has been making quality bicycle parts for over 20 years and now they have a new product "dropping". The SDG Tellis Dropper Seatpost is an incredibly reliable dropper seatpost that works drop after drop. It is a cable-actuated hydraulic cartridge dropper post that is designed for trail, all-mountain, and enduro riders.
