From the District description
"These super light bars are double thick and oversized so
will not work with Baby SCS or HIC."
What does than mean in scooter world?
I imagine it would be the same for any Y bar design- does this limit your choices too much?
Everything is a Trade off when dealing with metal and strength.
Aluminum has to be quite thicker to equal the strength of steel- Mild steel or Chromoly.
...but it certain circumstances it is all you need and works perfectly.
So when is someone going to make some Carbon Fiber bars

it's only money
