Leatt Gravity 31. 8 Stem Low Stack, Max Adjustability If you've ever cut a steerer tube a touch too short, or just want more flexibility dialing in your cockpit height across different builds, the Gravity 4. 0 is the stem you want. Its 27mm stack height keeps spacer options open whether the stem sits above or below them, so getting your bars exactly where they need to be is a much more possible option even on a tight steerer. The forged-and-CNC body delivers the strength this kind of riding demands, and the zero-gap faceplate with the 60mm clamp width keeps bar position locked under hard use. Available in 34mm or 44mm lengths to match how you want the front end to respond.
