Gravity 4.0 Stem - MTB Handlebar Stem 31.8 mm - Black | 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. MATERIAL: Forged and CNC-machined from 6061-T6 aluminum DESIGN & CONSTRUCTION: Match your handling preferences with three available lengths: 34mm for increased steering response / 44mm matches fork offset for balanced, neutral handling / 54 mm for improved climbing efficiency and more predictable control • Very low stack height increases the range of height adjustment and is compatible with short steerers • 60mm clamp width for maximum steering precision • Faceplate bridge increases torsional strength and is compatible with accessory straps • Zero-gap faceplate clamp design INTENDED USE: Certified to EPAC Gravity Category 5 standard • Designed for e-bike, downhill, enduro, all-mountain, and trail riding SPECIFICATIONS: Length: 34/44/54mm Bar Diameter: Ø31.8 mm or 35mm Rise: 5mm Stack Height: 28mm (34/44), 30mm (54mm) Weight: Ø31.8 mm bar version: 34mm-134g / 44mm-150g / 54mm-168g Ø35 mm bar version: 34mm-146g / 44mm-154g / 54mm-172g
