Got a bike designed for flat bars and you wanna run drops, maybe you have T.Rex arms, maybe you just ride bikes with long ass top tubes, or maybe you are running wide drops with long ramps? Who knows but I personally love this stem. Gets my bars just where I want them.
Steer tube needs to be cut down to 50mm. But comes with a spacer if you have commitment issues.
1 1/8 threadless filet brazed.
Fits a 31.8 bar. ( You can buy shims for smaller diameter bars.)
Will make your bars sit around 125mm above the top of your head tube.
