Ive hadthe h36 for a couple of years now and alays thought the same, until I compared it to a regular bar stem combo.
I think the difference comes with the width of the top of the ‘bars’ as my 90/390 was literally mm’s out with the same stem bar. because the top ofthe bars are so wide people tend to measure midway but you really need to measure to just past the T where the junction is.
I love mine
