Hi, it was not so much 'need' as 'would like' a dropper. As a not quite so sprightly 73 year old I find that lowering the saddle a little when on off road trails allows a quick 'dab' if necessary. It is also convenient at T junctions when waiting for traffic. I doubt it will ever be used in traditional Mountain bike mode .Well executed and presented! Enjoy your new addition!
Out of pure curiosity; why do you need a dropper on a bike like this?
