Remove the battery from the downtube using a 4mm hex key. Slightly loosen the fixing bolt of the cable guide where the dropper post cable enters the downtube. Loosen the seat post collar bolt. Locate the dropper post cable inside the downtube and gently push or pull the cable from this point to assist with lowering or raising the seat post position within the seat tube. Once the correct seat post height is set, tighten the seat post collar to 7Nm, tighten the cable guide and
re-install the battery.
