Added steering upgrade to my 5 last week. I’m not particularly tall (175 cm), but I always felt that the steering was somewhat ‘twitchy’. Quite honestly - it took 5 minutes. Big improvement to the feel of the steering and the ride position feels better - entirely subjective, I’m leaning a little more forward.
Only one criticism: the kit comes with brake levers and grips attached - an unecessary duplication of what is on the original bars. Seems like a waste of materials when I’m trying to save the planet.
Following my experience, you will be addicted with the special feeling of Strida rides 
Hi Palladio.
What is the ‘steering upgrade’? The cowboy handlebars?
