            .	Thomson Dropper Covert remote is one of the smallest and most ergonomic levers available
.	Lever works on the side of the handlebars and is shifter friendly
.	Works with Covert and non-Covert cable actuated posts alike using a grub screw to firmly hold the cable in place
.	Cable tension can be adjusted from the remote meaning removal of the post from the frame is not necessary to tension the cable
