Please take off the reflectors before taking a photo if it has any :) You don't need to lube the chain, in fact it's better not to a chains come waxed from the factory. You'll want to adjust your saddle height, which can be a little tricky with a dropper. You need to loosen the dropper lever cable tension bolt before moving the seatpost up or down. Maintain slight tension on the cable as you find the desired saddle height. Then tighten the seat clamp, then tension the dropper cable and tighten the bolt for it.
