Gravity 4.0 Stem - 31.8 mm MTB Handlebar Stem - Silver | Length 44 mm Leatt

Forged alloy stem with ultra-low stack height Designed for riders who need maximum cockpit adjustability, the Gravity 4.0 stem features one of the lowest stack heights on the market. Its ultra-low profile makes it ideal for bikes with short steerer tubes—especially when a fork has been cut too short—providing a far greater range of height adjustment with spacers above or below the stem. This allows you to fine-tune cockpit height with precision, even on frames or forks with limited steerer length. The 4.0 stem is forged for high material strength and durability, then CNC-machined to refine weight and achieve clean, functional shaping at an attractive price point. A zero-gap faceplate ensures even clamping pressure, while the wide 60mm clamp enhances steering control and precision. The faceplate bridge increases torsional strength and is compatible with accessory straps for mounting gear.
