Choose from 75mm, 95mm, or 130mm center distances and dial in handlebar height and reach to improve ergonomics, control, and posture without replacing the fork. The satin-matt black finish resists corrosion and wipes clean, while the four-bolt clamp design secures the bars with increased friction to reduce slippage.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the adjustable angle change my riding position?\u003c\/h3\u003e\n\n\u003cp\u003eAltering the stem angle changes both handlebar height and reach, letting you move between a more upright, comfortable posture and a lower, more aerodynamic stance. Small adjustments change how your wrists, shoulders and neck are positioned and fine-tune cockpit feel for different terrain.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eAngle range: -40° to +90° for broad position changes.\u003c\/li\u003e\n  \u003cli\u003eThree length options (75\/95\/130mm) to modify reach.\u003c\/li\u003e\n  \u003cli\u003eAdjusts without swapping forks or spacers.\u003c\/li\u003e\n  \u003cli\u003eUseful for testing positions before permanent upgrades.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat sizes and compatibility should I check before ordering?\u003c\/h3\u003e\n\n\u003cp\u003eThis stem is designed for 31.8 mm (1-1\/4\") handlebars and a steerer tube diameter of 28.6 mm (1-1\/8\"). Confirm both diameters on your bike to ensure correct fit.

The four-bolt faceplate increases clamping force and friction, helping prevent rotation or slippage under load while remaining serviceable for maintenance.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eMaterial: high-grade 3D-forged aluminum alloy.\u003c\/li\u003e\n  \u003cli\u003eFinish: matt black for corrosion resistance and easy cleaning.\u003c\/li\u003e\n  \u003cli\u003eClamping: four-bolt design for stable bar retention.\u003c\/li\u003e\n  \u003cli\u003eSuitable for MTB, road, BMX, and fixed-gear bikes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs installation straightforward and reversible?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the stem installs onto the existing fork steerer and clamps to the handlebar with four bolts. Typical home mechanics can fit this with common hex tools; orientation and angle are easily changed later so you can experiment with fit without permanent mods.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eMounts directly to standard 1-1\/8\" steerers.\u003c\/li\u003e\n  \u003cli\u003eSimple bolt torque sequence for safe installation.\u003c\/li\u003e\n  \u003cli\u003eAngle and length changes reversible for fit testing.\u003c\/li\u003e\n  \u003cli\u003eIncreased clamp friction reduces vibration-related slippage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: Cyclists looking to fine-tune handlebar position without replacing steering components will benefit most. The GEWAGE adjustable stem suits riders who want quick ergonomic adjustments — commuters, weekend mountain bikers, road riders experimenting with fit, and urban cyclists upgrading a fixed-gear or BMX cockpit. If you need a lightweight, sturdy riser with broad angle range and a clean finish to match many bikes, this stem is a practical upgrade. Always verify handlebar and steerer diameters before purchase and follow torque specifications during installation.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this stem fit my 31.8mm handlebars?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the GEWAGE stem clamps 31.8mm handlebars.
