Good morning,
Only a couple of weeks ago I did my first handlebar adjustment on a threadless headset, so I am like a new rider in that respect and I think that I get the point of the lower clamp from
Decathlon's perspective.
My first adjustment left me with a lose headset but I knew that the headset was lose and that I had done something wrong.
By splitting handlebar height and headset adjustment you are adding a level of safety for an inexperienced customer.
Coming from threaded I found the process odd, once understood it all makes sense, but I can see people getting confused and riding with a slightly lose headset.
I do like the look of your jobsworth toolkit as it seems to have a lot of tools, but I think that it has to be classed as a cost if the imaginary person buying the used bike is new or a returner. :-)
Can this thread can become a sticky and added to be others?
Bye
Ian
