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. The SDG Tellis Dropper Seatpost features an infinitely adjustable travel design, an intelligent keyway system that ensures minimal head play, and a sealed hydraulic cartridge system. The SDG Tellis comes with a 1x left side lever that mounts underneath the handlebar and has a cable and housing. For the cold weather riders, the SDG Tellis is cold-weather approved and is tested down to -20° C, or -4° F. If you're looking for an incredibly reliable and lightweight dropper seatpost that is loaded with features, then you'll love the SDG Tellis Dropper Seatpost.
