I saw a handlebar on Ali Express
The handlebars are 13mm higher like wings, so it might be similar to before the steer cutting or a little less, but I think I can restore it, so I bought it. I will install it and leave a review.
The angle is 7 degrees, so if you calculate the tangent, it's 1.7 compared to a 6-degree one, so it still goes up 11mm
