Existing TT bar and aluminum stem, aluminum handlebar
Most of all, since the existing handlebar width was too wide
I replaced it with an F1x handlebar 360
There were too many handlebars where I couldn't attach an OD2 steerer to the D-type even if I wanted to
At least I was able to get it at a reasonable price and installed it well
By the way, when I weighed the TT bar, it turned out... I had been carrying two aluminum handlebar sets haha
